So, here's the rundown.... 2001, AWM. few weeks ago, car was at the dealership... lean condition so they replaced all but one vac line.. left the hardest...heartless ******. car ran good, put in an APR boost guage... no problmes till I had a misfire on cyl 2 due to a loose plug popping out the coil pack. fixed that, no prob. Put in an Evo DV two nights ago, no problems, runs great. last night on my 2 hour drive back to boston, check engine light comes on... here's the results:

8 Faults Found:
17536 - Fuel Trim; Bank 1 (Mult): System too Lean
P1128 - 35-10 - - - Intermittent
16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 35-10 - - - Intermittent
16685 - Cylinder 1: Misfire Detected
P0301 - 35-10 - - - Intermittent
16688 - Cylinder 4: Misfire Detected
P0304 - 35-10 - - - Intermittent
16686 - Cylinder 2: Misfire Detected
P0302 - 35-10 - - - Intermittent
16687 - Cylinder 3: Misfire Detected
P0303 - 35-10 - - - Intermittent
16514 - Oxygen (Lambda) Sensor B1 S1: Malfunction in Circuit
P0130 - 35-10 - - - Intermittent
18010 - Power Supply Terminal 30: Voltage too Low
P1602 - 35-10 - - - Intermittent


DAAAAAAMMMNNN.... so I'm thinking that one old vac line is causing the lean condition, and my O2 sensor is bad.... would either of these cause my random misfire? what about the power supply terminal 30 low voltage?

im not happy.... could my EVO DV be leaking? maybe I didnt tighten down the clamps enough?

PLEASE HELP!!!

thanks guys!

 

When I had my leakdown & compression test

Later I found I had a bad coilpack

 

one bad coilpack caused multiple misfires on all cylinders?

 

I got misfires when I had the Leakdown & compression test on all cyliders

A week later I got a flashing CEL with a single misfire on cylider 2...bad coilpack

My mechanic forgot to clear the codes after the tests, therefore got all the codes a week later and caused me to panick

 

cleared the codes and re-gapped my plugs to .028. they were opened up a little more than that. I figure the new DV holding in more boost blew the spark out. The CEL originally came on during extended highway driving last night. As for the O2 sensor fault.... well, if it comes up again, that'll get replaced soon.
