The car bucks a little bit but that's not what's really confusing me anymore...

I've tried alot of different things to resolve that but lately I have a check enigine light that goes on and off primarily when I'm either slowing down or sitting still....

well I popped the hood to check it out and when I closed the hood it was like the impact of it closing made the car idle REALLY low...like 200 or 300...

I popped the hood and slammed it again and the idle went back up lol. I have no idea what's going on.

 

You probably got a bad connetion, but who knows... i know i got a bad ground that comes and goes, lights dim for a split sec the next its fine...

 

i say check all of your grounds also

 

Sounds like something COULD be loose in there. Go over all the harnesses and connections. Check your grounds.

 

yea check ground, happened to my 240 back in the days. bad ground
