Hey all, long story but, I installed a new starter and when cranking down the positive terminal on the starter I didn't realize it moved my positive battery cable to make contact with my headers and it melted in half. It did short on my headers and I've had a misfire since..what systems should I check for electrical damage?
thanks for the help,

Might just toss in a new icm if all the plug wires are good .

 

where is the icm located? Plug wires all seem fine, just mostly worried about "torque spikes" I'm having when coming to a stop. Have to really hold my brakes down in traffic when it happens.

 

Are you saying it has an idle surge or misfire ?

 

both, have misfires definitely, the idle surge i think is what im dealing with since my car will try to accelerate when in 1st below 10mph. Only when cold though. It's definitely a surge but quits when I'm fully on the brakes

 

You might isolate the misfire to a cylinder by doing a cylinder drop unplug each plug wire one at a time. Figure out that first before seeing if the surge is gone or a vacuum leak.

 

I was talking with one of my co workers about it and he says to swap the iac valve to see if it stops, said something along the lines of the voltage drop could mess it up. What sucks is i just replaced it

 

Command the oac in then unplug it. See if it still surges. I don’t think it’s a iac issue

 

what do you mean by command it in? I don't have any tuning or ecu programs or anything fancy to mess with the computer. I only have access to tools for mechanical work lol

 

Do you have access to a jumper wire or paper clip. Koeo jumper the aldl a to b. The iac is commanded in. Unplug the iac connector and start. See if it still surges. Sounds like a lean surge and ecm is trying to stabilize idle and can’t.

 

I'm sure I do have a leaky injector, I tested my fuel pressure at prime and it starts dropping almost immediately. She idles a little under 40psi. I do know the Bobby pin trick and that's how I read my codes, so I need to start her with the iac removed?
