In Reply to: How do I check to see which sensors are going bad when talking about my VE heat soak problem? --> posted by Aaron on June 27, 2002 at 13:52:03:
: I am sick of this and I want to fix it. I ran a 15.44 w/ 2.41 60' last week at the drag strip. After I ran that time, I let my engine warm all the way up and did two more runs. 16.24@86.73 w/ 2.52 60' and then a 16.16@86.85 w/2.51 60'. That's almost 8 tenths of a second off my 1/4 mile time. And one full tenth off my 60' time. : Can some people chime in to tell me exactly what sensors can be bad that could cause me to lose this much power? My VTC's are ticking very slightly only some of the time. Also, please tell me how to test different sensors to see if they have gone bad. And what else could be contributing to this problem? I have a 92 SE Auto w/ 115K miles w/ HAI, Y, UDP, adv timing w/ 93 octane. Thanks. : Oh, also, my friend mechanic is going to bring home this VERY expensive computer device that hooks up to my ECU and it will give you a read out of what is wrong. I think it's a Consult device. Will this tell me which sensors are causing my loss in power?
If that equipment is good enough. Verify that the timing is being pulled back more than necessary. If yes, then start checking the sensors that would affect such a thing. ie.. coolant temp sensor, detonation sensor, maf, o2 sensor, we have barometric sensors?, etc....
