View Full Version : Stalling problem... possible causes?

i've been having a problem for a couple months where usually after driving kinda hard for a little while, then trying to accelerate at lower RPMs the car would feel VERY sluggish for a short amount of time, then gain all its power all of a sudden and take off like normal, usually after 3k rpm or so. well today it seemed to be slightly more obvious than usual, might have somehting to do with the fact that i had been driving for almost an hour straight of city driving because it was becoming worse and worse the longer i had been out. keep in mind the problem is almost non-existant on shorter trips. earlier on i had gotten a pretty good idea that it was my spark plug wires/distributor cap,rotor (haven't been replaced in quite a while). but i have yet to change those (planning on ordering soon if that seems like it could be the cause of my problems).
well later on today i got around to attempting to remove my upper timing chain guide, but unfortunately, after removing ALL the valve cover bolts and such, i got screwed when the last 2 bolts holding the injector conector housing wouldn't budge :mad: so i pretty much gave up for the day and put everything back, but i could only get about 5-8 lbs of force on my front 2 bolts before they felt like they were starting to strip my head, so i laid off and tightened the rest without the torque wrench and just the ratchet and lighter force.
here comes the fun part... i took a quick run out to get some chinese food and my car almost stalled out everytime when i was cruising and would push in the clutch to slow down or stop. instead of the rpms coming down to idle, they would drop like normal then go past idle and either stall or almost stall. i also noticed that my idle was around 1k or so when i started the car.

what do you guys think my problem is. here are my ideas:
1) my first thought (i hope i hope) is that when i was trying to take off my valve cover and took out my spark plug wires i somehow bumped or mesed with the connections between my distributor and the spark plug wires and thus cause'd a loose connection, making my former problem much worse.
2) another idea i was having was that the valve cover seal was leaking due to possibly stripping 2 bolts and thats causing an oil pressure drop possibly?? i didn't think this was a possibility since the valve cover seal is a "low pressure" area.
3) another possibility i've considered, but i'm not too sure about is that while trying to get the damn injector connector housing off i somehow loosened a connection there. this is a good possibility since i was messing around in that area for a good half hour trying to get the 3 bolts off, but i really don't think i did any damage (other than a small crack around the inside part of the plastic). is there a way to check and see if this is my problem cause i am clueless to this part of my engine. if it means anything my car revs/idles smooth and i feel like i have plenty of power most of the time.

thanks for bearing through my explanations and any thoughts are appreciated. if u need anything cleared up be sure to ask because i know i'm not always clear. i'm plannin on taking a look tommorw but if i don't know what to look for i'm gonna be pretty clueless

well i'm pretty sure i found my stalling problem, i was playing around with the injector wires today and everything was fine until i got to this part right here. whenever i shake it the car starts idling VERY rough and will stall if i shake it enough. is it possible to just rewire this plug or would i be better off getting one out of a junkyard? by looking at it, it didn't look complicated at all, just 8 wires if i remember right...

Don't junk it just yet!!
Chances are all it needs is a good cleaning because the contacts are not clean and getting intermittent signal...Go to your local auto parts store and pick up some 'electrical contact cleaner'. Open up the connector and give the insides a good soaking. Then take some fine steel wool or equivalent to clean off any oxidation or nastiness.

That should do it.

i had a similar problem a couple months back, except it just happened after 10 hrs of straight driving, not after touching anything. it would do the exact same thing. when i engage the clutch the rpm's would just drop all the way to 0 and stall. i ended up just not driving my car too much and keeping a "manual" idle by keeping my foot on the gas. after a week everything was fine... i have no idea what happened... it's a "self healing" car!!! haha.
