  1. Well I cleared it a bunch of times and it always returned. I'll run it for a bit see what happens now after the swap. . . And....the solenoids not activating is a totally different issue? Or is it related?
  2. Cylinders 4 and 6. I swapped the coils and plugs with 1 and 3 and ran the car for a bit with no cels. So not sure what that means.
  3. Ok, Getting back to the issue here. (I took a break) So I have 2 issues the 1.misfires and 2. the solenoids not turning on? I thought the solenoids not engaging would cause the fault code but I suppose the solenoids aren't activated until a certain RPM is reached. V
  4. Same results with new relay. I then checked voltage on each wire of bank 2 solenoid. 14.9 red/grn with little or no fluctuating when revved. 14.6 on brn/gry with lower voltage when revved...maybe down to 10v So kinda lost here. I guess I could swap plugs/coils see if it follows, doubtful cause they were replaced. Then check for low resistance in the wires from solenoid connector to pins for DME. Was looking at wire diagrams but couldn't find pin # on any DME connectors for red/grn and brn/gry wires.
  5. Ok, Ill report back after I try the new relay. Thanks again. V
  6. Right so one part of the circuit is shared...so it still might be the relay....no?
  7. Crap...had my hopes up. Maybe theres 2 circuits downstream from the relay...spitballin here!! I'll try the relay anyway. See what happens. Maybe the relays totally shot, I did have a hard time starting at one point. Car cranked but wouldnt start. Then it did after a number of attempts. Briefly looked at wiring diagram. Both Red/Blu are shared with both solenoids maybe thats the issue with the relay?
  8. I ordered 2 Bosch relays for 17.00(one spare) it was easier than checking all the voltages, especially on bank 1. Figured I'll give it a try. Would a bad relay cause the solenoid in both banks not to activate? Thanks V
  9. Ok maybe that's the wrong one in the trunk I found, I'll look under dash and get back. Thanks again
  10. Ok, thanks John great help. Where is this relay bay in the footwell near the fuse box. Don't recall anything in the engine bay.
  11. Hobbyist mechanic so bear with me. ...1st off not too sure how to check voltage on each pin. Do I ground multi meter to engine and just use the pos lead on multimeter to check voltage from those 2 pins?(one at a time) I just had the multimeter connected to the 2 pins on the connector is that incorrect ? I started investigating DME relay ...is that the same as the ECM relay? There's 2 relays near L tail light in the trunk. One green w 5 pins and one black w 4 pins. Is the 5 pin one the ECM relay? Other may be fuel pump relay. Also remember both solenoids don't activate with the Durametric. I just checked bank 2 solenoid w the 9v battery and it activated as you know. Didn't try bank 1 solenoid cause it's not as easily accessed. Would a failing ECM relay cause both not to activate, if so maybe that's the prob. I noticed it's also intermittent, CEL lights blinks sometimes then goes to solid CEL and then it just goes off sometimes.
  12. .25 volts at idle to 5v when engine is reved over 3500rpm. Can't identify correct pin for checking resistance. Looks like red/grn and gry/brown wires at solenoid connector.
  13. New batt and alt. So 12v at solenoid connector?
  14. I only connected a light to the solenoid harness. Was dim at idle then grew brighter w increased RPM's. Ok..so check for resistance between solenoid connecter to appropriate pin going into DME. Only 2 pins. Then back probe solenoid connector with engine running to see voltage. What voltage should I see.?
