misfire

Hello, so I’ve been having this issue with my ca18det where it will start to hesitate and misfire trying to rev over 4K. I’ve sorta narrowed it down to tps I have tested it and everything seems okay. I’ve heard it needs to be set to 0.5v closed but the issue I’m having is I can only adjust it to...

Hi all, My Silvia has recently developed a strange problem. It misfires and runs on 2/3 cylinders all the time its running, except when the key is turned to the off position or removed, it will then run normally for about 3 or 4 seconds before dying. I have checked that im getting spark on...

Morning guys, I've lurked on the forums for some time now researching the S bodies more than anything else. I bought a bit of a dog if I'm honest. I was aware that it was rusty and had a boosting issue but it's one of those cars where the more you dig, the more you find. I'll start up a prog...

Right then folks, I have been a long time member on here, but as you can tell by my post count, I do a lot more reading and learning than contributing! However as the title suggests I have a problem with the RB25DET in my C35 laurel and it has got me utterly utterly baffled. Basically...
