TPI 42 and 43 codes error
Hello friends
I have trouble with engine.
At first i want to say, that i have L98 from vette 1987 rebuild to MAP and ECM 1991 Camaro.
Check engine light say, that we have 42 and 43 errors.
I think the reason is that i have distributor from vette and ECM from camaro.
Can it be the reason of trouble...
Buy the way, at 2000 turnaround i see Exhaust Manifold that was WHITE color, not red, not black - WHITE!!!!! Plastic parts was melt under the hood in few seconds

Hei devorced could and coil in cap will swap no problem. As long as the 4 icm wires are hooked up correctly. Have you gone through the trouble tree for 42 & 43 ?

Check the ks ohms from the center pin to housing or ground. If it’s from tpi maf it will be 100 ohms tpi ss 3.9k .
Sounds like your super lean and need to check fuel pressure or possibly replace your injectors. Does the engine have a lean miss?

What does it mean "As long as the 4 icm wires are hooked up correctly" ?
