2.0lt. engine missing Options

[Tab914]

Forgot to mention also get an occasional puff of smoke on ignition.

i'd go ahead and pull the dizzy and replace the trigger points. it'll cost you about 120 buck, iirc. take the dizzy apart and clean it while you're at it.

meanwhile, does your mps hold a vacuum?

[Tab914]

The pressure sensor seems fine. What is a good way of testing it? By dizzy you mean.......

[nebreitling]

distributor.

set the car to TDC. pull dizzy, noting it's orientation. plug up the hole with a rag or something. don't move engine or car while dizzy is out. take apart, clean, replace FI trigger points. replace dizzy the way you found it. set timing and dwell again.

might do the trick (might not (IMG:style_emoticons/default/unsure.gif) )

re. MPS, borrow/steal/buy a vacuum pressure pump. pump up some pressure, see if it leaks down... hope it doesn't ($$$$)

hey there,

I have the very same problem with my 2.0 djet. at around 2700 rpms it bucks at steady speeds. Drove to France and back (1900 miles) kept the revs above 3000 and no problems that way. (IMG:style_emoticons/default/wink.gif)
still haven't figured out what causes this.
my tps sensor tracks are worn, might also be dirt in there making a short and fooling the ECU...
about a year ago I checked all the electrical (and vacuum) connections and problems seemed to be less only shortly though
will be back at it this winter, new vacuum hoses and some other stuff, maybe a new wiring harnass (working on it right now)

If heard of more 2,0's with djet having this problem, it seems to be quite common...

hope there's a fix for this..... (apart from a 3.0 six (IMG:style_emoticons/default/cool.gif) )

interesting to read about this!

sounds like TPS fo' sure

Tab914,

Canadian Tire has vacuum gauges in their Loan a Tool program. Pull a vacuum and see if your MPS leaks. If so, that will cause your car to run rich. It could be the problem. Give it a test and let us know. Good to see another Teener in Canada. I drove through Banff last month. If I had of known there was a fellow 914er there, I would have stopped by and said hi. I usually get out that way once or twice to ski in the winter, too.

Good luck,

Well it looks like the problem has been resolved. Here is what was done; new distributor cap, replaced a plug wire that looked suspicious, took off and opened the TPS and cleaned all it's contacts, moved it's brushes so that they sweep on new lines and reinstalled as per specs. Rechecked timming, dwell and idle. Here is what I think is the clincher; I discovered a resistor between the head temp. sensor that didn't seem to belong and didn't show up on the electrical diagrams. After test on both sides of the resistor discovered that it was sending erronous signals to the ECU. Removed it and and reconnected sensor wire directly to the harness connector. Took the car out for a test drive and no sign of the problem. Took car up to temperature where it would buck before and still no symptoms. So, looks like the problem is solved but am keeping my fingers crossed that this is not only temporary. I want to thank you guys, especially Nathan and also Slits and Royce. Hey Mike, next time you are in Banff skiing look me up. I am the daylodge manager at Banff Mount Norquay, one of the ski resorts here. I'll hook you up with some free ski passes and a few beers while we exchange 914 stories over lunch or apres ski. We should exchange emails so you can contact me before coming up. Again guys, thanks alot for all your input and help. If you have photos of your cars I would like to see them if you can post them. Here is one of mine. Cheers, Dominic.

Dominic,

Free passes would be awesome! I would owe you a few beer for that. If you're ever out this way, look me up. I'll slide you an email sometime soon!

What year is your car? I forget which, but one year 2.0 is supposed to have a resistor on the CHT.

And you're welcome!

[mike_the_man]

73 should have the ballast resistor, I believe.

[Tab914]

This one is a 74 2.0lt. Also have a white one back in Ontario which is a 73 2.0lt. Will be there in a bit and will have a look.

[Tab914]

Any time Mike. Do you know Norquay. It's the one that is actually right in Banff. Just before Sunshine. Make sure you send me that email and we'll hook up.

[bondo]

Someday my wife and I plan to visit Banff. It looks like an absolutely beautiful place. What's the best time of year to go if you don't plan to ski?

[Tab914]

Well, if you like fishing, hiking, golfing or even just sightseeing in nice hot sunny dry ( very low humidity ) weather, from June to mid September is great but the town is very busy with high tourist season. Otherwise you can do all those things in a bit cooler weather in the Spring or Fall when the traffic is a little lighter. The shops aren't as busy and the tourists attractions aren't as crowded. But in all honesty, it's quite breath taking here pretty much all the time. Moved here from the east ( Ontario ) 8 years ago with plans of spending one year in the rockies. Now I can't tear myself away. If you ever do come around let me know. I'll show you the good bars in town.
