Ok, here goes...the car won't start quit a bit, when I shake the negative battery terminal hard it seems to help the car start. Once it starts it runs fine until it gets hot in the engine bay, then things go nuts, every two minutes or so while driving all dash lights flicker for a millisecond and the car stutters hard also for a millisecond. Other times when the engine bay gets quite hot it will go haywire with the dash lights going nuts and the car sputters to a stall. I'm forced induction with an Odyssey slim battery and many many many other performance mods, so any info anyone needs to help please please ask...p.s....I've done a quick look over bay wiring and nothing seems glaringly wrong.

 

list your grounds

 

Test ur alternator. Maybe the internal voltage regulator took a poop. Idk. Lol

 

List my grounds???....you list em!!!!!....lol. all grounds are stock minus my sub ground in my trunk....ill double check that.

 

just trying to help w/e not my problem

i bet you clean all your grounds you solve your problem

 

Fixed, please close. Fix was: the shop I had swap my clutch out, I'm guessing, raised the bell housing back up after clutch install...mounted bell housing and didn't realize the forgot to connect the negative battery ground on the housing...and there is no way to get to it without removing the starter and in my case, intake pipe and blow off valve. With that said I think they got lazy and hand tightened it cause it was loose, so I removed the before mentioned parts, tightened the ground down and all good as it stands now, consistent starts, no dash flicker and good boost when the engine is running hot.

 

your welcome
