So I just got my PCM from frost which did a mail-order tune for me and I tried starting the car up but all that happens is that it cranks and then a couple of loud pops(backfire?). All I have on right now is the headers so could that be the problem? I'm gonna try to connect the ORY to the rest of the exhaust tonight and try again tomorrow morning. Also the car is throwing three codes which ar: P0122 P0342 P0118. I've looked them up online but have no clue what they mean haha. Any input is greatly appreciated!

Thanks,

Aaron

What type of car and what are the modifications? Did you just finish the modifications and this is the first time trying to start?

To help get you started, see below.

P0122
Low voltage on the throttle position-check to make sure it is connected.

P0342
Cam position sensor-make sure it is connected (this is probably why you are backfiring, if it isnt connected)

P0118
Engine coolant temp-check to make sure the sensor is connected.

I would Check you Cam Sensor Plug. Make sure its pinned correctly in the plug. I had a new harness pinned wrong in the cam sensor and mass air plug.
