Hi,
I'm new to the forum but not new to stangs. I recently did a cam install as well as a tune. My mods are as follows (engine wise anyway) custom grind cams (about a stage 2 comp) trickflow 75mm tb/plenum, jlt ram air intake, mac LT headers, o/r h pipe, slp lm2 exhaust.
now i just recently had a problem where my car would hunt alot at idle, thought it was the tune but the problem persisted after the tune, turns out i had a bad o2 sensor, so i replaced both, car ran fine, then i took it out a week ago, and i all of a sudden got this p0300 (random misfire) error and a p0100. my car RAN LIKE CRAP. it wanted to die at idle so i had to keep revving it to keep it from dieing. the SES light stays on even after clearing the code it comes back. now the weird thing is this, it seems that now the problem only persists when the car is at operating temperature. cold it runs fine, aside from the normal stumbling and uneven engine shaking that it always did, but when ive been driving it for a while the problem seems to pop up. i checked the cop's and plugs were just replaced not too long ago, i did a few data logs but i dont know what to tell whats good and bad, so for beginners luck, please someone share their knowledge on this topic.
thanks in advance.
