Ok, new to the site but not to the world of mechanics. I am wanting to know if anyone else has had this issue.

I have a 92 4x4 extended cab with an auto trans and the 3.0 vze. I just bought the truck and wanting to work out a few issues. The engine seems to run pretty good. The head gaskets have been done already and I have one vacumm line off. I found out where the vac lines goes which is to the bvsv so that will be no issue but, I still have this #5 cylinder issue.

I have pulled the plug and found that there is more than enough compression. I pulled the plug and found the plug it to be firing through the wire all the way down. I can take the wire off the distributor for #5 and there is no change in the running of the motor. I am leaning towards the fuel injector for #5 being clogged.

The truck was not driven alot and sat for about 2 weeks before I got it. It ran great when I test drove it but after driving it 2 hours home somewhere along the way it began the shaking because of the #5 cylinder not contributing.

Any ideas? Has anyone else had this issue?

if you have good compression and spark, you must be losing fuel to the cylinder. check your fuel injector and wiring to that injector.

That's what I was thinking. It's a pain to get to the odd number injectors under the plenum. I did get lucky and ended up with a full set of freshly rebuilt injectors including the 7th injector for less than $50. Just figured I would see if anyone else had the same issue. Thanks.

I would be thinking the same thing. I can't recall how hard it is to reach without walking outside and popping a hood, but able to reach it to just to tap it while running to see if it comes back around so you can yell "IT'S ALIIIIIVE" ?
