Q: Car hesitates and jerks with rising RPM

asked by on

My 1997 toyota tercel 1.5l manual transmission start faulting around 2,300-2,500rpm on any gear. At first it seem like a fuel problem/vacuum so I start replacing the following Fuel pump Fuel injectors Fuel filter Fuel regulator Map sensor Throttle position sensor Idle control valve I haven't noticed any vacuum leak(I spray at idle to see and nothing). But every time I cleaned the area around the throttle seem to help a little but then goes back to the usual problem. To me it seems like something it's clogges(it doesn't have a catalyst converter). Can someone tell me what else to do. I ran out of ideas
