1994 Ford Explorer Q&A
1994 Ford Explorer Question: Idle Rough
We just replaced the mass flow air sensor and the purge flow solenoid in our 94 explorer. Before changing the mass flow air sensor the truck would run with it unpluged, but plugged in it skipped and spuddered real bad. The purge solenoid was broken on one of the vaccum hose ends, so that was replaced. It is still running rough with these changes. Not near as bad but still rough. Any suggestions? - Shadyspatti
If it was a "reconditioned" air flow meter I have seen poor quality air flow meters fail right out of the box. You will need to look for a vacuum leak failing ignition component or fuel issue responsible for the poor running. Do you have a workshop manual? Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info or there is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subscription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try http://bit.ly/mitchell_repair_manuals_online and get an online repair manual subscription. - patrick mannion
