Hi Paul no just replaced coil packs and dfi mods with genuine Delphi parts relevant or not any input has to be a positive thing when you trying to problem solve you haven't so thanks for taking the time to get back to me cheers mate

No problem mate, did replacing the dfi and coils fix it? There's plenty of knowledgeable people here to get advice off. Car wiring can be tricky because you have wires for things like low reference, 5volt reference's signal but once you get your head around it, it doesn't make any difference, it's still ******* confusing...hahaha Something that helps me is what they call a powerscan tool.

Immortality, thanks for providing the download mate. Un fortunately i dont have enough storage space to view it atm.
I'm only new to electrical commponents and testing them.
I came across a mutimeter at cashies a few months ago and taught myself how to sorta use it.
Youtube can be a great tool if you can weave your way through and sort out whats rigjt and

I don't know if this is relevant or not but I had a 1998 vt calais many moons ago and had dfi problems. The first time it happened, the car out of the blue started running rough. It turned out the dfi had developed some sort of problem. So replaced it and it was fine. Then around 3 months later same thing happened and it was the exact same problem with the dfi. So again replaced it but this time I bought a spare to have in the car so i could change it out if anything happened. Which it did around about the same time frame. So wacked the spare one in and brought another one but it never missed a beat again. And ironically, the spare one was a cheap arse Chinese one.
