Hi I recently bought a 91 Vn it was running rough and would die when I plant the accelerator, after about 5 minutes of running it would die completely. Recently put in new fuel pump, filter, coil packs/Dfi module, plugs and leads, o2 sensor and cleaned the throttle body and sensors out. It now runs abit better and doesn’t die after running for a while, but still is still very rough on acceleration and gutless when I plant it but doesn’t die. Just wondering if anyone has any ideas. Thanks

Is there a strong petrol smell in the cabin or engine bay?

I’m not to sure about the fuel pressure regulator, and haven’t/ don’t know how to bridge the ALDL to get codes. There isn’t strong fuel smell at all, and I have got a new tps and iac on the way
