Hi Supercharger yotas. I have a 96 TRD supercharger that I added in 2002 when my 4r had 120,000 miles. Recently I have been have my first problems with the engine missing when I get up to 2500 rpms. Wondering if anyone else has had this problem. So far I have, changed the fuel filter, fuel pump, fuel pressure regulator. Checked sensors, VSS, O2 sensors, cleaned and checked MAF sensor, checked for vacuum leaks. Unpluged knock sensors to see if that would stop the 2500 rpm miss. I did get a p0171 code once, but it didn't reoccur. Now the fuel trim readings and O2 readings seem normal. The MAF readings are just above normal readings for a standard aspirated engine I figure that is due to the supercharger. I have a exhaust gas temp gauge and the temps are normal. I'm about ready for the dynamite. Does anyone have experience with this problem?
