My '86 Camaro (2.8) runs good when cold, after about 10 mins it starts to run rough and the SES displays code 32 & 34. I know it's refers to the EGR & MAF. Any clues on troubleshooting this?

 

Checking the EGR is simple.

Get a finger under the EGR valve and press up on it. If it doesn't go up and down freely you need to take it off and try to clean it. Also while it is off look for a tear int he diaphram. If it has a tear just plug the vacum line until you can get a new one.

As for the MAF I have no idea. i have a SD setup and never played around with a MAF.

 

Does it run rough and stall once it warms up. Garenteed your MAF sensor is gone. When the MAF goes,you car will hesitate, and cut out all the time, it becomes a pain to drive. The EGR can cause problems too, but this sounds like the MAF.

 

I will never stall. It just loses power. If I give it a load it will bog down.
