HAHAHAHAHAHAHA i dont care who you are, that was funny!

but for rizzle, i think its your computer, reason i say this is because my 1993 chevy 1500 suburban did the same exhaust leak then fine if you drove slower than an old lady, horrible if you drove normal (bogging down) then if you floored it, it all of a sudden ran fine and hauled ass! my suburban was throwing up a bunch of codes that were all checking out fine, (the reason for fingers to be pointed at the computer) so i bought a new computer and couldnt get it to run at all after trying the new computer. I was told i needed to hook it up to a machine mechanics would have to sync the new computer which i have yet to do.I will try to remember to post back with my results!

Thanks for all the responses. Im gna get at it. Thanks guys

What kind of air cleaner do you have, I have a 94 and broke down because of my 14" air cleaner was grounding out the coil wire, so I had to get a smaller air cleaner

ur truck also has two temp sensors. one in the head on the driver side and one in the intake manifold. if the one in the intake manifold is bad the truck will not run right at all!!! it is for the computer. it decides fuel air mixtures and timing advance or retard depending on engine temp. i had similiar problems as u guys and i chased everything else for weeks!! changed the sensor an BAM!!! RUNS LIKE A CHAMP! i recommend u guys try this before any comp swapping. its way cheaper!! hope this helps u guys! oh yea my burban is a 92
