Allright, heres the deal. I have a '94 Camaro. Auto LT1 etc. Not any significant mods. Recently, the car has been cutting out at full throttle and anything about 3,000 RPM. Also, I have a ticking noise (EGR?) when accelerating smoothly. I ran my car on a Pathfinder scanner and Code 48 came up (MAF) so i replaced the MAF sensor to no avail. Then code 32 came up (EGR) and I dont know where to go on that. I have good spark at the plugs, and I am in the process of replacing plugs and wires. Any help is appreciated, I need to drive my baby lol. Thanks in advance guys.

 

Bump! Need Help Asap!

 

When you replaced the MAF sensor, did the DTC 48 go away?

The EGR code sets when the PCM closes the valve while its operating, and doesn't see a corresponding change in the MAP reading. Could be a faulty EGR valve, a bad vacuum line to the EGR/solenoid, or carbon builup on the EGR valve pintle and the manifold EGR port. The valve might also be stuck open.
