'90 Legacy w/a '93 EJ22T swapped in.

 

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 driving last nite w/the car running well - didn't die once- the CEL comes on but the car continues to run fine.

 

I pulled the codes and found:

Error 14-17 for Injector #1-4

Error 23 - MAF Sensor

Error 32 - O2 sensor

 

 

I've read that the MAF could cause these symptoms?? I've got another MAF I can try.

 

 

Also, the O2 sensor isn't working right as the voltage doesn't change...I'm using the Revscan software from Revtronix that can read multiple parameters..... 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.

 

 

Thanks for any feedback!

I've used the bosch O2 sensors and not had any problems with them. I would just make sure you get it with the factory plug installed. They are avail. without the plug, but the wire colors are different, so it makes the job a bit tougher.

 

Your problem sounds pretty indicitive of a maf failure though. I'd check that.

 

And figure out what in the world is giving you four failed injector codes. I've never seen four failed injectors at once.

Swapped the MAF and installed the Bosch Universal sensor..yeah, it's a PITA and I got it wrong the 1st time....car wouldn't even run.

 

But the idle is much better, smoothest it's been in weeks. And NO CODES after a 15 minute drive.

 

I'm guessing the injector codes were related to the failure of the MAF/O2?

 

Thanks,
