as far as i know the car has nothing done to it. gave it a tune up around 3 1/2 weeks ago . i checked the spark plug gaps for the first 3 on each side but not the last 2

Its a weird problem. My car would jerk bad while getting on it. It was my A/F ratio itwas at 10:1. I dont know how it happend but it was like that when I got my new motor after blowing the old one up from a supercharger, but everything was returned back to stock and somehow the A/F got there. Maybe you have clogged injectors or getting to much fuel. Check injectors or take it to a dyno and have them run a A/F run on it. Hope that helps some.

I am taking it that ur check engine light is on. If it is, when your check engine light comes on it pulls timing and adds fuel to the motor for safety.

IF you have a check engine light on get it read. If you dont check for pending codes?

all of my spark plugs are the white colored meaning that the A/F ratio is too lean. i think i might need to clean my injectors
