Posted by: bd1308 May 18 2005, 10:45 PM
is this a fuel delivery problem (done everything short of taking the gas tank out and getting it...."boiled?") or is this something like a CHT....it books from 0 to around 40...but...it's almost like the rings are shot, just no compression...i mean i can't even accelerate when going up a interstate hill....maybe it's just time to do all three.......
Posted by: mk114 May 18 2005, 10:57 PM
Mine did the same thing turned out to be combo fuel regulator and vacumn leak
but run compression check to be sure
Posted by: Bleyseng May 19 2005, 07:38 AM
and check the vacuum advance cuz that will cause the same (no power) symptom 
Posted by: bd1308 May 19 2005, 08:16 AM
well if i unplug it, i believe it runs better than when its plugged in....cause i did that and it idled like its supposed to....when its plugged in, it idles at like 300RPM....its barely turning over...and the idle screw has ZERO effect on the idle....even if the TPS is unplugged. would the compression go to the hell in like 500 miles? b4 it was great, now this started. i think i might try a regulator cause its random enough to be the fix, yet easier than getting compression stuff done
Posted by: Bleyseng May 19 2005, 08:33 AM
I would check your timing and set it at 27 degress BTDC @3500 rpms with the hoses off and plugged. Then set your idle rpms.
Low idle like 300 rpms would indicate the timing is off to me for starters.
Posted by: bd1308 May 19 2005, 08:34 AM
i thought it was 27@3000???? *sigh* back to the start.....

Try using the lower speed power more effectively.

It would be help ohter readers if you gave info on your setup. which engine ? which fuel system etc ?
I suppose that if no info is given it makes sense to assume "stock everything", but a lot of people in the club have modified their cars.
Hope you resolve your problem.

where are you that 50mph is "high speed" ? 
Posted by: bd1308 May 19 2005, 08:52 AM
it feels like its lean when goign fast.....i'm going to try a regulator off of the 1.7.....it's my gut feeling.

do 100 in a bettle, then we'll talk about feeling like you're going to die!
and we only had lap belts!

Gut feelings are usually incorrect with regard to D-Jet.

That's great. I did 100mph in my lowered '63 karma ghia convertible w/built up 1600 engine and no factory supplied seat belts. I was young and dumb.... and lived to tell about it.
Posted by: michel richard May 19 2005, 09:40 AM
Adjusting the fuel pressure would make a difference accross the range of power settings and rpm situations. You may want to rule out ignition stuff before looking at the injection. Are your plugs clean ? nice fat spark ? vaccuum advance working properly etc . . .
Just my .02

Did you change something before this occured? What was the last thing you touched before the problem started?

When you are finally done screwing around with that Broken Dizzy please ask me to send you mine.
If it runs good vacuum line disconnected and runs like crap 300 rpm with the hoses connected YOU HAVE A BLOWN DIAPHRAM IN THE ADVANCE UNIT.
I and the rest here will be so happy when you break down and put good parts in your car. 120 MPH in my teener last sunday. held it there for about 3 minutes till I caught the next traffic group. 
But I don't know what I 'm doing

I agree, seems like djet related problems usually occur only at idle, or affect all RPMs something this RPM specific is probably ignition related. Do a complete dizzy swap, and make SURE the hoses are in the right spots.
Posted by: bd1308 May 19 2005, 04:35 PM
the idle isnt the issue though...the issue is the lack of power. I will try a dizzy swap. 1.7 dizzy's arent compatable with 2.0 dizzy's right...due to the difference in circumference of the dizzy body??

I'm pretty sure the diameters are the same. Advance curves may be different, but not by enough to keep it from running. As long as it has the trigger points in the base, it should work, at least enough to see if you have a dizzy problem.
Posted by: bd1308 May 19 2005, 05:24 PM
yeah, i just thought the rotational diameter would be different, due to the difference in plug firing(time between cylinder fire)....but i guess i was wrong....lemme pop in my 1.7 dizzy then....

i don't know what the heck you guys smoke back there, but boy, you should be selling it on eBay and making a fortune
if you did any research, you'd notice that the 1.7, 1.8 and 2.0 all share the same cap, rotor and other consumables.....
Posted by: bd1308 May 19 2005, 06:02 PM
it's the air man.....and the reformulated gas. i'm putting in my 1.7 dizzy then.

Woah, wait a minute ... haven't we covered this dizzy issue with a couple hundred posts a dozen threads ago already? And STILL again with the dizzy?
Anybody else getting dizzy?
Posted by: Rand May 19 2005, 06:14 PM
Bet a dollar when this gets fixed completely, the points would be reliable again.
Not that you'd want to put them back in...
Posted by: bd1308 May 19 2005, 06:15 PM
i dunno...everything looks great inside of that distributor.....all oiled and sexy and such, but still all i get is hassle....
Posted by: Bleyseng May 19 2005, 06:15 PM
Put the 1.7 dizzy in as they are damn near the same other than minor advance differences (so what).
After you get it in and set the proper timing, check the spark on a extra plug by pulling the #1 plug wire and putting on the extra plug which is grounded to the engine good. Have your helper turn over the engine while you look at the spark. It should be bright and a good clear spark.
Now that its running, check the fuel pressure witha pressure gauge. should be 29lbs.
Take it for a test drive.
BTW if the vacuum advance blows out its not that critical as the dizzy is mostly mechanical advance. The weights do stick and the advance won't work, so the engine has not much power do to the timing being stuck at 5 degrees AFTDC

Posted by: nebreitling May 19 2005, 09:05 PM
you're gasping at straws because -- it seems to me -- you are not troubleshooting ultra-methodically. your car's problems could be any multitude of things. you'll never know until you STOP throwing parts at it and start throwing tools, knowledge, research, and logic at it.
maybe that's just a false impression i've got, though. good luck, bro

Here's a deal 50 bucks for my Proven (rebuilt) 1.7 Distributor.Cap rotor, FI points, a set of plug wires, I'll put your Petronics in it for you. It has good points in it now. Time it probably have to adjust valves too. Plus pay my gas I'll deliver it AND GET YOUR CAR RUNNING.
Any other trouble shooting goes by the hour. I ain't cheap BTW.

dont be an idiot.
we have a known 914 pro ready to make a house call!!!!!!!!
gee! lets see here. get a car running, or try to fix it yourself...
call the man and pay his gas!!!!!!! and buy him alcohol too
in socal, we do these things for free....JK

Posted by: bd1308 May 21 2005, 04:41 PM
dizzy...finally replaced with another good one. Pertronix is on hold for now....no thanks mueller on the baptising.....it's only a car ya know 
thanks for the help most of you......
i need these 
and not this
Posted by: Bleyseng May 21 2005, 04:45 PM
can you go over 50 mph?
Posted by: bd1308 May 21 2005, 05:11 PM
well i could before....it's just that the acceleration was F L A T....and money was not plentiful.I fianlly grabbed the dizzy out of the storage unit and all is well....the 914 books!!! 
Posted by: lybones May 27 2005, 01:59 AM
I had the exact problem with my 1.7 before I yanked it out. I drove the car to a local mechanic who found out it was my Fuel Injection Trigger Points located in the dizzy. I would have never guessed. Replaced the points and the car ran good again. Don't if someone else had mentioned yet, but it's my two cents. goodluck
Posted by: bd1308 May 27 2005, 07:34 AM
okay here's what i believe my problem is. My harness connections (to the plastic connectors) have obviously seen better days. The trigger point connections (all 3) were trashed, some still connected by only one or two strands of copper. I quickly fixed them with a crimpable butt connector after trimming down some new replacement "ends". Also happened on one of the pins for the mps too. I believe that this wasnt the best way to attack my problem, so I think I'm going to either re-do those connections, get a bowlsby harness or both.......
