1996 VS Commodore V6 Misfire?

The guy who is selling that module has some really bad reputation comments I dont think I could buy of them.

haha didnt even bother reading his feedback at your own risk i spose not factory GM part either

have you tried cleaning all the engine earths ? especially the one under the coils and DFI. Could be worth pulling the coils and DFI off the bracket then remove the bracket and clean the whole lot.

 

[Changa]

Yeah ok I might try pulling off all of it. I have no idea where anyof the earths are though so I cant do much about that.

Yeah there was some pretty bad stuff said about that guy like wrong items, cheap imitations, stuff that didnt even look like the pic. I dont think I could go through that guy.

you will find the earths as you go. there's one under the coils, one near the battery and a few on the engine .... looks like a small wire bolted to the engine. Check if they are rusty or dirty.

Ok thanks for that

how is yor harmonic balancer looking i have seen this before where thehamonic balancer was running that far out it was chewin up the crank angle sensor on a car with similar symptons to yours

 

[Changa]

Yeah it has a tiny bit of wobble but I think that is normal. I havent checked the crank angle sensor as I have no idea how to know if its stuffed or not. But I am fairly sure it has to be an ignition problem, hence either the DFI module, coils, leads or plugs. Went to a mechanic he said it cant be the plugs with the symptoms described and I have checked the leads and coils which just leaves the DFI module. But I have heard a stuffed crank angle sensor can do similar things.

Hey guys thought Id say I have fixed this problem, ended up being my own fault. I purchased a new modded memcal tune from delcowizzid and after taking mine out I started removing my stock chip to send back to him as its an exchange. But his first chip was buggered so I had to resolder in my stock chip back in, I thought it worked fine but it did drop out occasionally (half stall once it fully stalled). When I got a new chip from delcowizzid the problem vanished. Hence the way I came to the conclusion that I had either incorrectly soldered in the chip or I damaged it with the heat of the soldering iron.
