I have removed and cleaned throttle body, idle air control valve n the EGR valve. And replace all of those gaskets.I replaced MAF sensor. I have also removed the upper air intake and cleaned it all out and replaced the gasket. I also ran seafoam through the intake. Replace the coil PAC and put on new plugs and plug wires. I have also replace the fuel pump and the fuel filter.
I have tried to hook up Scanner OBD 2 and it says error cannot connect. So being the year that I have it also has OBD1 so I did that and pulled codes 172, system lean bank one. 136, system Lean Bank two. So I removed both O2 sensors and clean them both. 167, TPS did not exceed 25% rotation. 411, can not control RPM during test. 214, CID circuit failure. 122 TPS circuit below 0.6 volts. 332 EGR did not open fully or respond during test or did not open intermittently EVR or PFE. 532, data communication link or electric
instrument circuit failure. I am not sure how correct these codes are beings that I pulled them on multiple occasions. I am going to buy or rent fuel pressure test kit so that I can check the pressure at the Schrader valve.
have the same problem?
