Okay, I have a 06 TR with 115K car died one day on the way into work brought my car into Monro muffler and fuel pump **** the bed (now a 255 walbro) had them do the timing belt. next day fuel filter o-ring popped out of the filter so I change that, had issues ever science the timing belt done with cyl 4 misfire, at this point I've changed injector, spark plug, and coil pack. Any ideas short of motor ***** the bed. I'm trying to justify how this all happened at once shy of them... I just want my car to run the way it did!!
