I think steve's onto something. If when slowly covering the top of carb and idle smooths, could be vac leak or air/fuel mixture screw adjust. I've had lots of success in smoothing out an idle that way, can't be any vac leaks however. Keep us posted and good luck

Ive seen raw egg whites seal leaks as well. Bottom line is i would never use a sealer unless it was an emergency in the middle of nowhere

Yesterday was a really rough day. Timing belt was off 1 tooth. Re-aligned and problem gone. Thanks for sharing my stress and those few ideas

going to tear covers down first thing this am and "tripple" check marks. will look at the lead wire for crank and check all pins and grnds. Appreciate the input so far and will let yall know what mistake was made.

car ran well upon arrival. Put timing belt, valve cover gasket, spark plugs and fr struts, and had battery disconnected. After work was completed, the car starts and runs for about 3 seconds then cuts off. It will re-start and repeat every time as if the alarm system is active. Was hoping someone ha...

sound like something from drive train touching body. Fuel trims and other data would help

I'm thinking crank sensor. Had couple others here in the last couple years with similar issues, and both needed crank sensors. May need to just change and see, due to lack of frequency of symptom. Hate educated guesses but sometimes have little choice. Good luck and keep us posted as to the fix

You should be able to power balance with a scan tool (modis, verus etc). If not, try unplugging inj 1 by 1. If the shake doesn't increase with eng rpm then maybe Steve's on to something. Good luck

I'll assume that no vac hoses got pulled off.

compression shows all cylinders with in 25% of each other, 25% of 180 is 45. 135 min

Yeah Steve, I was going to mention cracked cap, although what i re-rread looks like cap was replaced after tranny. I've seen them up against the fire wall with tranny out. Identifying the cylinder will certainly help

I believe the radio has more than one power supply. One for power with key on and one for memory, power always. If either one goes out then so will radio, just a thought.

Both sensors were new, and had the caps on the threads. The leads were even still folded and taped. I did see in identifix where there were several hits for similiar problems on the trucks, if I remember correctly. I am not bashing bosch and have used them in the past w/o problems. Just wont be usi...

never had any issues with the bosch 02's yet, but i will be watching and pre-testing from now on. Thanks for info

I assume there are no vac leaks. Block learn should be about 128 if not mistaken. Does eng get up to temp? (t-stat) Is ect reading properly? Front 02's greatly affect runnability.

Steve, you ought to submit some of you modified and special app tools, or ideas, to a company, maybe make a few/lot of bucks for the idea or proto-type.

My advice to anyone doing this job? Take it slowly and carefully. Don't get angry or pushy. /////////////////// In other words, "have patience, don't be one" lol?

I'm in agreement with steve. If the connection was melted then it most assuredly shorted the wires and probably that circuit to pcm. Keep us posted

sounds like your test gpcm must be faulty, glad you got it fixed

Found that the port was 3/4 restricted once the plenum was off. Soaked in de-carbon over weekend, drilled, honed, scraped, chisled, punched, kicked and a few other tricks i could think of. Came out very clean and now map and egr and 02 readings are perrrrfect. Did this one for free and got a happy c...
