First thing to rule out is tires. Swap the front tires left to right and retest. While swapping the tires give the suspension and brake parts a real good look over and manipulation.
To properly sync these you need to use a scope to bring the camshaft position sensor and crank sensor into a certain range. That procedure is out there. Now something you can do that is quite easy and might fix the issue. Use a scanner and clear the KAM (Keep Alive Memory). This should be done...
There are two things that can happen with the Fuel Pressure Regulator. One being that the diaphragm splits and allows fuel to be sucked into the intake creating a rich condition. Another issue is if the regulator does not open. This will cause a spike in fuel pressure and push more fuel through...
Over time the oxygen sensors slow down, which leads to less engine efficiency. To test an O2 sensor, you would use a scope. Stab the throttle and measure the time the O2 goes from rich to lean. This will be measured in milliseconds. If the sensor is within range, it is working fine and should be...
Yes, you want to disconnect the MAF before starting. This should make the ECM use a fixed set of parameters to allow the engine to run. That is, if this year allows it.
Another thing to check is the EVAP solenoid. If this is leaking(stuck open), this will cause a lean condition at idle. These...
A quick check for the MAF is to disconnect the MAF, start the engine and see how it runs. If it runs good, then the MAF is bad. If it still runs poorly, need to check for vacuum leaks.
