2002 Chevrolet Silverado 1500 4x4 Z71 5.3 Vortec Engine. 109000 miles. Only on cold mornings/days does it stall and idle really rough and missfire. Here is the strange part: if I unplug the MAF sensor, it runs fine. If I plug it back in, goes right back to crap. So I thought i had found my problem and replaced the MAF Sensor but to my surprise it did the same exact thing. It is throwing a coolant temp sensor code so maybe that is the culprit. My question is if it is a bad coolant temp sensor, why does it run fine when I unhook the MAF? I also tried unplugging the coolant temp sensor but it still does the same thing if the MAF is plugged up. |

I have a 87 tbi truck and I am installing a 94 tbi motor. Most items look as though they will swap out but the 94 seems to have two temp sensors and the 87 only one? Do I use the 87 computer (1227747) or should I use the computer that came with the 94 (16146299) and just not hook up the temp sensor that is in the left side cylinder head as there is no provision for it on the 87 wiring harness. Thus only using the temp sensor in the inlet manifold? Thanks............ |

| did u check the relays for the driver door? when i recently put window tint on my truck i found 2 relays one for the driver side door and one for the passenger side so i pulled both of them so my tint wouldnt get messed up. relays should be under the hood in the fuse box driver side. | |
