Whats up guys. So as the title states I have a misfire when the car is warm or sometimes randomly. Sometimes is a little hesitation at low rpms when I first got the car, but that seems not as bad after everything Ive done so far. It also cuts out or stutters above 4-4.5k rpm. NO CELs. A quick background on this car. I bought it 2 weeks ago for 1000 dollars, it was sitting for 2 years in the guys yard as he bought a new car and didnt drive it any more. So here is what I have done so far.
NGK BPR6ES Spark Plugs Gapped to .28.
Wires
Air Filter
Oil Change
Fuel filter is going to be done Wednesday.
Im going through the maintenance guide as we speak so I know what to do so far which I'm addressing. and have yet to do. The car does have a boost leak I'm assuming so i am doing a test this week to find it. My boost gauge reads -12 to -17 vacuum at idle. -22 on deceleration. Car boosts to 9psi. Seems like the car spools around 3k rpm The car is mostly stock with only a aftermarket exhaust.
Now I had a "aha, oh shit" moment to rememebr that there was a sensor unplugged on the car. So I just went out to the car like 10 min ago to take a picture of it, then after some more looking around I noticed 2 more sensors unplugged which I have no idea how I missed before, feel kinda like an idiot but. What exactly are these 3 sensors? I think one is the knock sensor which could cause the misfire in the first place, correct? Why it would be unplugged I have no idea. I'll post back after the BLT and if I remember anything. Thanks Guys!
First sensor I found
Second sensor I found, which is this the knock sensor? Has 2 wires coming from it
Third and final sensor I found, no idea what in the hell this one is
