Default Don’t know much about LS1

i am the worst with cars which is why I am here. I have a 2000 corvette ls1 swapped in a 1995 1500 pickup.

The truck has been rough idling and running like crap lately.

Z06 cam

what we have changed.
Maf
map fixed an issue where it would bog out while driving.
O2
tps
plugs and wife’s
crank sensor

Random misfire code.

Truck will idle ok sometimes but most of the time really rough. Same with driving. It will run fine and then after a stop or turn on and off runs like junk again

ive read a lot of threads here all with different fixes. Most of which I changed.

Any ideas?

Check to make sure all the coil packs and wiring is good and that all the connectors are firmly seated on the injectors. I had one of my injector clips somehow come off the injector.

I appreciate the response and will do. Do you think the pcm lost its tune or is bad?

A bad connection somewhere, check and re-check wiring, grounds etc. Wires can be broken off too, without the insulation being damaged. The pins inside the connectors can get misplaced.

A bad tune makes the problem repeat itself at the exact same situations over and over again. There is always a pattern to be found when it comes to software.

When it runs fine, try to make it run bad again by twisting and bending all electrical connectors and wires.
