Replaced TPS, still have accel. hesitation
I bought a '01 Altima GXE at an auction. I've replaced wires/plugs/distributor,rotor/valve cover gasket/fuel filter<--unnecessary.
When i 1st got it the car had a severe hesitation accelerating. Everything I've done has helped bit by bit. I cleaned the EGR valve, the sensor had lots of carbon on it. I replaced all vacuum hoses visible. I also changed oil and filter.
The car has 212,000+ miles.
I brought the car to a mechanic and he told me my Throttle Position Sensor was bad, so i replaced it. He also said my catalytic converter was clogged. I removed it today only to find it wasn't. I am soaking it in strong Dawn water anyway.
I tested the intake manifold gasket for leaks especially around the furthest right cylinder (standing in front of the car) Nothing happened when i sprayed starter fluid around each intake. I have read on the internet that every 2001 had a problem with the intake manifold gasket. And i doubt the owner before me changed it, considering the condition when i got it.
Do u think its the intake manifold gasket causing me acceleration hesitation? It is accelerating in spurts. Thanks -RacerX309
