914World.com _ 914World Garage _ Engine almoswt quits at 4000 rpm

Posted by: meares May 25 2005, 01:49 PM

just put the GD 2.0L in...got it back yesterday..now it almost quits at 4000 revs...it's strong until then and then it sounds like it loads up with fuel and fowls the plugs....feels like it running on 1 or 2 cylinders this is REALLY starting to piss me off!!!!!!!!!!!!!!!!!!!!!!!!!!

Wait wait wait... injected?

Is it stumbling? If these are the symptoms, sput... taa taa...sputt...aaa... and injected, may be a simple TPS cleaning/readjustment.

?

That help at all?

It could be lots of things, but when I had a similar sounding problem it turned out to be the trigger points. One each of the two contact sets triggers 2 injectors. If the rubbing blocks get worn down, 2 cyls. stop firing...seems to happen first at higher rpms for some reason.

i just turned the grey knob at the "box" (i guess control panel/box) all the way to right...clock-wise. it idles better but DAMN i smell A LOT A LOT of fuel..i'll turn it back down......it seems like now that it 'loads up' at 2 or 3 revs now instead of waiting for 4000. ..............Where are the trigger points?...THANK YOU !!!!!!!!!!!!!!!!!!!!!

are the points in the dist. cap?

The trigger points are in the distributor but all the way at the bottom where you have the 4 or 3 contact plug. You will have to remove the whole thing. Try and clean them because they're much more expensive than the ingnition points.

My 2.0 was doing the same thing. I changed out every thing except the trigger points. Got feed up with it and took it to get serviced. they replaced the trigger points and now it runs great.

if i go to an XR 3000 and all the related side items that it needs will it eliminate the need for the fuel inj. points?

Posted by: lapuwali May 30 2005, 02:06 PM

No. However, trigger points generally only need replacing every 40-50K miles, and never need adjusting.

are the 1.7 and 2L interchangable?

Let us know if changing the trigger points solves the problem.
I've had a very similar issue and have not yet resolved it.
Maybe mine's the trigger points, too.

It amazes me how many FI problems are fixed with new trigger points. I recently had a stumbling problem at a certain rpm range which progressively turn into a no run issue. I went through a bunch of ignition and fuel troubleshooting before I finaly changed out the trigger points to a spare I had. Fixed the problem immediately.

I will now always carry a spare set.
