Hello, and I want to thank anyone that has information that may help. I am glad I found this forum. My car is a 350 tpi 1988 iroc, I am having a problem after start-up. The check engine light comes on and the car starts acting as if it is bogging down. I ran a code on it, and it comes back 33. I have replaced many of the vac. lines and fuel pump relay just in case. Also have bought a new maf but it still performs poorly. Please any help! Thanks Scott, your friendly okie!

 

Did you try replacing the MAF relays?


This thread may be of some help to you:

Thank you, I will give that a shot today!

 

Well, that must have been it! I am so happy for your help. I drove the car for a good hour or so and everything acted normal! Thanks for the help!!!!!

 

Cool Did you replace both relays?

 

There are two? I replaced the one that is in line with the three on the firewall(drivers side). Where is the other one?
