Wildman Posted January 3, 2010 Share Posted January 3, 2010 From what your write, and from what you change out, parts wise, what your experiencing sounds like a plugged EGR valve. A quick (and cheap) test is to pull the vacuum line off the EGR valve, and plug the line with a screw/bolt, and see how it runs. A plugged EGR will choke out the engine, and not let it run, or even start. Link to comment Share on other sites More sharing options...

Geonovast Posted January 3, 2010 Share Posted January 3, 2010 92 does not have an EGR. That was done away with in 91 with the HO system. From what I can decipher from your question, it sounds like a poor spark issue, or perhaps a timing issue. You've replaced a lot of stuff, but you missed some of the cheapest and easiest stuff. Replace the spark plugs, cap, rotor, and wires. Link to comment Share on other sites More sharing options...
Wildman Posted January 3, 2010 Share Posted January 3, 2010 :doh: I forgot about that :oops: I'm going to go craw back into my Renix world now :dunce: Link to comment Share on other sites More sharing options...
jimoshel Posted January 3, 2010 Share Posted January 3, 2010 Hint. Use golf tee's. They're tapered shape allows them to fit more lines better. Link to comment Share on other sites More sharing options...
kylineman Posted January 3, 2010 Author Share Posted January 3, 2010 Sorry guys I failed to mention the plugs distributor cap and rotor button have been changed I am not for sure if it is possible to check the timing on a vehicle that u can't keep running I have gone through every thing you guys have mentioned I just hate to take her into the garage may be my last resort thanks for the good information Link to comment Share on other sites More sharing options...
aemsee Posted January 3, 2010 Share Posted January 3, 2010 You changed pieces, but have you checked the vacuum at the MAP and for the correct power and grounds at the TPS? When it dies, is it instantaneous, or does it stumble them die? Any black smoke out the tail pipe? What do the plugs look like after it runs and dies a few times?

jeepcoma Posted January 3, 2010 Share Posted January 3, 2010 Any chance the vacuum line to the power brake booster is off/damaged? Serious vacuum leaks will cause poor/impossible running at lower RPMs. Definitely put a vacuum gauge on there anyway and see what's going on. If you can get it to run at 2000 rpm you can get a timing light on it and see what it's doing, and then slowly back down the RPM. If you can't read the markings at that rpm you should at least be able to see if it's jumping around or nice and stable. Disconnect the vacuum advance and put a gauge on it.

88pioneer Posted January 3, 2010 Share Posted January 3, 2010 sounds a lot like when my altenator went in my cherokee, it sputtered and stayed running above 2000 but once it backed off it shut off. Blew a lot of black smoke too, might be your problem, not sure Link to comment Share on other sites More sharing options...
