1991 running problem
I have a friend that i am trying to help him with his 1991 vette. when the car warms up the motor starts to miss and light dim. No codes or check engine lights, and i checked the fuel pressure and all the individual injecters and plugs (they are brand new but I checked them out anyway). Could this be a EGR problem?
a little help would help and thanks in advance.

It almost sounds like a bad ground too. These cars do some funky stuff when a ground is bad. Do a quick inspection of all the grounds. I had the same type of problem and chased it to a corroded ground
Good Luck!

could a EGR valve be a problem because it happens only after the car warms up?

A problem like this can have so many causes and buying and installing the parts is not the best method to address your problem. Find someone with a scan tool, buy them a beer and ask for their help. If you lived close to me.....it would be a done deal
