I just bought some new acdelco plugs Part Number: CR43TS from advanced auto parts and a acdelco oil filter Part Number: PF52

I bought plugs and oil filter to do a tune up on my blazer because when i start the engine it studders and bounces for a few seconds very rough idle until i give it a lil gas

Anyone know about these acdelco products i heard there good but i will find out tomorrow when i change them out

 

they are OE equipment so you should have no problem with these parts....

 

i hope so

 

Those would be the best parts to use for it. ive heard guy who run on the strip that still use the AC Delco Parts on their vehicles.

 

You can't go wrong with original equipment tune-up parts. But your problem sounds like it could have a leaking fuel pressure regulator to me.
