Hello all,

I have been having issues with the ol' MIL coming on....and the car is idoling somewhat rough at times...and REALLY rough sometimes(AND WHEN IT DOES, THE LIGHT GENERALY WILL FLASH......when you first start it in the morning, it runs like a dream....as it warms up (even a little), you begin to notice it running rough. If you go to the exaust and listen..you can tell it is not running properly by the sound and the smell (smells rich and burns the eyes a little)

I had it scanned and the mechaninc told me I had "random misifires"....and said to change the plugs and wires. Did it....put it the irdium plugs and Accel 10mm wires. Car still runs the same.....MIL stays on. Took it to Autozone....the guy was kind enough to let me know that cylinder 2 was misfiring. So...I swapped coil packs around to see if the misfire would jump to a new cylinder. Nope....stayed in cyl 2. I got the codes reset.....and drove for a bit......went back to AUtozone...still on Cyl 2.

NOW.....I finally boned up and bought a scanner (the Actron CP9145)...yeah I know...not a snap on or mac....but it got good reviews on the web...and in some cases, found data that the snap on did not.///so, I bought one.

Scanned Still have a P0302 Mod$10 Cylinder 2 Misfire Detected (AND WHAT THE HECK IS THE MOD$10 TELLING ME?)

ALSO a pending code (same as above...but with a p/d on the end of P0302

It also mentioned something about the EGR valve 2 acting up....but when I reset the computer...and drove in to work today (about 65 miles)...that code has not returned...only the misfire codes remain. Maybe not enough time has passed yet for the computer to have it fault enough times to report)

Here is what the Freeze Data Review screen says for the time of the fault detected on cyl 2:

TROUB CODE P0302
ABSLT TPS % 0.0
ENGINE RPM 736
CALC LOAD % 2.7
MAF LB/M .64
MAP "HG 13.0
COOLANT F 172
LT FTRM1 % 10.2 (THIS ONE INTERESTS ME....DOESN'T THIS MEEN THE CAR IS RUNNING REALLY RICH AT THE TIME ON FAULT? AND THIS IS THE LONG TERM DETECTOR...WEIRD

VEH SPEED MPH 0
FUEL SYS1 CLOSED
FUEL SYS2 N/A


I have also did a veiw data scan on the way in to work this morning....and I noticed that when I was running at higher speeds..and accelerated hard from there....somtimes the Fuel Sys circuit would go to open...and when I let off the gas some.... it would go back to closed agian. In the manual. it indicates that when the Fule Sys Status goes to open, "Module is operating in Open Loop control strategy. The vehicle has not yet satisfied conditions for module to go to closed loop" I dont know if this is right or wrong for the car to do this.....but I wanted to give ALL of the info I could to the forum as to result in a solution.

Last night, I checked the rsistance of the injector at Cyl 2...against the others ....the resistance is the same. I checked the injector for continutiy to ground....it has none which is normal.

Wow.....sorry for the download....but man, I am getting desperate here. Please help however you can.


Thanks!!!!
