Error codes - Injectors, MAF and O2
Posted: Wed Sep 30, 2009 3:07 pm
I've had some recurring engine issues the last few weeks where the engine will just die. A couple times while idling, a couple times while accelerating, and 2 times when coming to a stop/slowing down @ an intersection. I've also had it cut-out for a brief second, but continue running.
Car always starts right back up and NO CEL.
After doing some WOT runs last nite w/the car running well - didn't die once- the CEL comes on but the car continues to run fine.
Back @ the house I brought out the laptop, started the new Revscan software and pulled the codes:
Error 14-17 for Injector #1-4 (history)
Error 23 - MAF Sensor(history)
Error 32 - O2 sensor(history)
The injector errors may be left over from when I had bad injectors a few weeks back....I can't recall if I cleared/reset the codes or not.
But I've read and Lee/Skid542 confirms that the MAF could cause these symptoms.
Also, the O2 sensor isn't working right as the voltage doesn't change, but doubt it would cause the car to stall.
Anyone think the Bosch O2 sensors are OK? They're avl. locally for $50 and I don't have time to order one....leaving for VACA tomorrow.
I've got another JECs MAF (Revtronix chip) I can try, plus try a new 02 sensor.
Thanks for any feedback!
