I drive a 1996 geo tracker 16 valve 1.6 liter. I live on a small island where the engine never really warms up. The egr tube becomes restricted with a gummy carbony sludge about every 1000 miles. There is very little blow by. Has anyone attempted to insulate the erg tube in an attempt to keep it hot and reduce condensation of exhaust?

where is the ignition sensor located on an 1989 olds delta 88

I went to a mechanic a month ago and replace the alternator because my battery light came on.  After about one month, the battery light came on again.  I went to the same mechanic and he said that the oxygen senor is faulty.  If I unplugged one oxygen sensor and I did not fix that one oxygen sensor. Will the car still run and won’t shut down?  What are the problems that the car might cause?

car runs & drives for awhile then losses power & stalls, replaced throttle postion sensor, had & still has diagnostic code P0171 system too lean bank 1, replaced fuel filter & had black gunk dripping out of it, think could be plugged fuel strainer or plugged fuel regulator screen or failed fuel regulator or plugged fuel return line or leak in vacuum hose to fuel regulator, any ideas?

I have a 1996 Jeep Grand Cherokee and I need to know where the crankshaft position sensor is so I can replace it. Please be as specific as possible.

the O2 Sensors are shutting off the injectors early  thinking it is getting too much fuel…. The ECM isn’t seeing enough Air Flow so it won’t allow anymore fuel to be added. Does this thing have a MAF Sensor on it ????
