Thread: need help with 240

BEEN THERE!!!!!!!! this sucks finding loose grounds. in my case it was the MAIN ground. you know the one that goes from the intake manifold into the engine bay. i had a hyperground that went from my intake manifold to my shocktower under the strutbar. i guess it was loose so sometimes it would run VERY rough. and i relocated and i never saw this coming but it ran a HECK of a lot faster and fuel efficient. also ... it didnt bog on me on the higher rpms such as yourself. so try that start from the most simplest grounding posibilities to the hardest.

its a loose ground wire mayb, had tha same problem but wrecker my 240 b4 i could fixed, damn
