Oil Change [reset computer]

Denny Nelson · 03-25-03, 08:23 AM

Just changed oil and went to a 10 minute type place [friend-takes extreme care with my cars] BUT does not know how to reset the computer. Does anyone out there know the steps for a 1996 LT4?

Also just told that I can pick up valuable horsepower with change in a couple of computer chips. I appreciate any reply to that as well.

5000 miles on my LT4 Convert since 11/14/02 and LOVING every minute of it [no tickles--err tickets-- yet. Did get one in my Camry. Soooo embarrasing]

1. Turn the key to the "ON" position, but don't start the engine.
2. Press the ENG MET button on the Trip Monitor and release it. Then, within five seconds, press and release the ENG MET button again.
3. Within five seconds, of Step 2, press and hold the RANGE (1990-1991) button or the GAUGES (1992-1996) button on the Trip Monitor. The CHANGE OIL light will flash.
4. Hold the RANGE or GAUGES button until the CHANGE OIL light stops flashing and goes out. When the light goes out, the Engine Oil Life Monitor is reset. This should take about ten seconds. If it doesn't reset, turn the ignition "OFF" and repeat the procedure.

This is for my 94 LT1, I think yours should be the same.

Danny, The directions for resetting oil light are in owners manual , if you have one. In the 96 I don't believe there is a chip to change, you have to have the computer(obdII) reprogramed. I'm pretty sure about that but if I'm wrong someone will correct me. Good Luck, Guy

Your right on about the chip issue. The last year the EPROM was accessible was 1993. The 1994 thru current must be reprogrammed..... good and bad about that.. the good part is the programming allows one to "experiment" so to speak with tweeking the systems, the bad part is the programmer itself is pretty expensive.
The other bad thing is: If the reprogramming is not done correctly, (other wise known as have a tuner do it correctly) things can go wrong in a hurry. Incorrect fuel mixtures, spark too far advanced, redline reset too high and many others that can be detrimental to your engine.
