not familiar with what that is since im new to these cars

the donor car is bone stock BTW, wanna make sure everything runs perfect before i swap it into my race car.

it ran like this before i swapped them, couldnt the broken balancer have caused things to be thrown off?

can i swap in my zzp tuned pcm from my 98 gtp? i tried it once but it wouldnt start the car, are the interchangable or is there a procedure?

are they special scanners or sumthin? i dont wanna drop any money on the donor car if i dont have to. Just want some reassurance that everythings good before i swap in my other car and have to pull it for some reason again know what i mean.

unplugged the sensors on the tb and started it up to see if it made any difference which it really didnt, just idled a little higher and SES came on. Plugged everything back up, disconnected the battery and the SES still comes on so maybe whatever is wrong finally popped up, so ill have to get it scanned t/m.

i think the SES is from taking off the secondary o2, im gonna take my chances and swap everything into the new car and save all the sensors off my old motor. Dont have time to have the car scanned right now since i need the motor out so i can scrap the car ASAP

Finally got the motor in my race, but before hand I pulled the remaining rear plugs to find one more ngk iridium plug and 2 old school ac delco plugs w litterally a 1/4 gap and worn out tips. Also ported my sc outlet and put a new gasket on. Thing fired up right away and throttle is real responsive, took it down the street and the things a beast.
