Ok, having car issues again. Car is running like it's missing on one cylinder. It started doing this the last few times I've drove it. On startup it would have a miss, and the car would run rich 10.0. It would do this for roughly 25seconds, clear up, and run smooth with afr's at the normal high 14's. I figured it was either the spark plugs or wires.
Thursday, preparing for the March fun run, I gave the car an oil change. I started the car to let it warm up a little so the oil would flow out easier when I drained it. I saw that the check engine light came on. I continued/completed the oil change, and was going to change the plugs to next day. I didn't bother checking the codes at that time figuring I was going to do it the next day when I changed the plugs.
Friday I change the spark plugs. I inspect each one. I also look for any evidence of arcing, and couldn't find any. Started the car and now it has a continuous miss that doesn't go away.
Check for codes and came up with; 24, 34, 42 & 52. Damn, almost hit that lottery!
Things that I've done:
I unplugged the MAPECU, and reinstalled the stock AFM & readjusted fuel pressure for it. Cleared the codes, and check them again and it displayed the same coded.
I looked at the knock sensor rewired that I did and noticed a hose clamp prong touching the inside the butt connector that I crimped on there. I wouldn't think that would short anything out because the hose clamp is just on a rubber hose. I moved it out of the way. I haven't check any of he wiring with a voltmeter at this point.
I removed all of the spark plug wires and check them with a voltmeter. They all checked out fine.
I inspected the coil pack per TSRM. It checked out fine.
I bought a timing gun and adjusted timing. It was off by a few degrees. Started the car up and it still runs with a miss.
I pulled the plug wires off the coil one by one while it was running, and they all get spark. No irregularities.
Next thing I'm going to do is do another leakdown test, and see what cylinder #1 is up to. Then I'm going to go through the wiring with the voltmeter and make sure everything is sound.
