The prefix portion of the ID code tells you the assembly plant code, M is Gm Of Mexico T is Tonawanda. The difference is the plant it was built in.

    What type of car is the replacement engine out of? Is it front wheel drive also? is it close in year or appearance? Same type of fuel delivery setup?

    If the price is right and the donor is in good shape I would go for it. You have your old engine to swap off parts that are diff. but it should be almost a drop in.

I have a 1993 Chevy Lumina engine 3.1L> I am getting a code 12. What is that and how do I fix it?

Code 12 will always be the first code you get which simply meams that your computer and PROM (the memory chip in the computer) are working properly. If you did have a trouble code, how it works is the code 12 (1 and then2 flashes) would happen 3 times. Then after the code 12 any other codes would start. They would also flash 3 times and then move on to the next code and when all the codes were done there would be a longer pause then normal and code 12 would happen again 3 time and the cycle would start again. In other words if no other codes are coming up after the 12 (3 times) you're in good shape and your computer isn't detecting any malfunctions. I hope this helps.

Check Engine Light Is On & Car Is Acting Strange

You need to find the source of the check engine light. Fortunately on the '92 you have OBD-I and can check this yourself. This site explains it pretty well...

but the code list is incomplete.

This place gives a more complete code list

Or this place has codes too.

The error code can point you in the right direction for which engine system has the problem, but you will need to run some checks to nail down the specific cause of the code.

Hi, could someone help me with the firing order of a 1990 Chevy Lumina power pack, please. Thanks

You didn't say what size engine you have, 4cyl. or 6 cyl.
The 4 cyl. is--- 1-3-4-2
The 6 cyl 3.1 is---- 1-2-3-4-5-6----- on the coil pack under the exhaust manifold is----- 1-4-6-3-2-5. If neither of these doesn't work, then you have a different engine.

Check engine light on a 1996 chevy lumina

Hi there .... the best thing to do right now is to take it somewhere like autozone and get the car scanned for codes. Once you have the codes you can post them here and we can help you with it. Without codes it is a little difficult to diagnose.
