Yeah... you're going to want to swap those with AC Delco parts as soon as you can afford them.

 

I will just depends on if anything else breaks first lmao

 

My 1991 had the same symptoms, only it never refused to start. It has 33,000 original miles on it now and the plugs, wires, distributor and rotor had to be changed out by the auto repairman. The mother in law never had it in for a tune up and she was the original owner. I traded my 2004 Hyundai for it and just got a few bugs to fix. It runs fine now.

 

33k on a 91... Nice!!

 

I know this is way off topic but how the hell do you take the vents out of a 1st gen blazer I am going to paint mine but I can't figure it out, do they just pop out or are there screws just wondering.
