I can not recall the exact codes, the individual that read the codes indicated that it was the intake air sensor (this is the one that sits almost infront of the firewall) after replacing that one It then came back as being the throttle postion sensor. As previously stated, these have now been replaced. I also metered the plug wires and I am reading 8 - 10k of resistance. Replaced the plugs, also replaced the fuel filter, Removed the ignition modules and tested both came back good. Replaced the fuel pressure regulator, Replaced the fuel Pump one month ago as the older one went bad, Opended the exhaust before the cataliytic converter and the same problem exists. I actually removed the intake manifold also, cleaned the ports and replaced the gaskets, visually checked the injectors and all looked fine, replaced the EGR valve. Checked for vacum leaks by spraying cab cleaner along the vacum lines no leaks present. Also I have checked the resistance of the injectors and eash measure about 12.2k of resistance the only other option I have is to take the injectors and have the thorugh cleaning done. Any other suggestions?
