put the ignition module on, and I immediately get a code 42, and the car is missing all over the place. The module I got was from a friend, its a wells brand, and it may be bad, or is it even possible to hook it up wrong? I'm sure i got it on there right.

Ok, finally got my hands on an ignition module, put it on, and am about to go test the car, wish me luck!!

Well, i buttoned the car up (reinstalled IAC) and started it and moved it into the carport. The SES light came on. CODE 22! TPS sensor circuit low! Gonna tackle that TPS here asap, mcasteel you were prolly right about the TPS all along First time I have seen any code other...

Prolly done for today on the active testing, will resume again possibly tomorrow.

Mine is pulling fuel apparently, but you may still be right.

And its a bad miss too, not some barely detectable burble, the whole car feels like its gonna shut off, and jerks like crazy. Doesn't pop or anything. The closest comparison I can get is like the power flickering during a thunderstorm, thats what it feels like, like someone is throwing a...

Gas is 4 days old, full tank from chevron I always use down the street. Fuel filter is new also. Car is not a daily driver, but gets used/driven no less than 30 miles of semi-hard use at least every three weeks, uses a tank of gas every month or so. I never get better than 8-9 mpg tho. I...

Ok fuel pressure dropped to 38 line off @163deg O2s 199-250 at idle IAC 26@ idle jumps to around 40 or so when the throttle is blipped cc seems the same TPS@ .42 jumps quickly to 1.6 or so when the throttle is blipped INT and BL stay 124 to 130 until I throttle the engine to around 2k rpm...

Ok. IAC is factory original IAC@ 163deg is 15-20, shoots up around 35-40 when throttle is tapped INT AND the BL both read as low as 112(!) when rpm is in the problem range, and throttle is depressed around 25% (This all took place in the driveway, I hope that doesn't make a difference) INT...

mcasteel, let me go warm the car up to give you a IAC reading. I have an aftermarket temp gauge, and it always reads the same as the SM temp gauge, if that helps you help me. I can go pick up a new ac delco TPS sensor if you really think it may be the culprit, but to my thinking, if the...

This is so confusing:p

The coil pack was changed, but not the module. The wires under the coil pack looked excellent, no corrosion at all, slipped on and off easily. You are talking about the ECM module on the passenger fenderwell? As far as I know that is original to the car. Would that cause a bad miss from...

Ok update: First a correction, the INT reading is pegged at 128, thanks to the TT chip, the BL usually hovers around 116 to 120 at idle. Fuel pressure is at 42lbs line off I don't know of any other way to test the EGR valve other than to unplug it and block it off? I unplugged it and plugged...

EGR test tomorrow possibly. I have determined the miss/stumble happens between 1900 and 2400 rpm REGARDLESS of throttle position. Like downshifting while coasting down a hill, you can hear the car falling all over itself, but since there is reverse stress on the drivetrain, it doesn't shake...
