OK...here's the latest. So far, replaced on the GP were the following:

2 Oxygen sensors (sensor 2 and 3)
2 Coil Caps (servicing bank 1)
PCV
MAF Sensor

I had shop diagnostics done, and the only thing they stated was fuel pressure was too low:42-44 psi where as it should be 48-55 psi. Of course they want me to replace the fuel pump for ~$500 all inclusive.

I also purchased a fuel regulator, but have not installed that yet.

One guy stated that if the fuel pump was bad, I would know it. Another stated that the injectors need to be properly cleaned. Any ideas before I sink more bucks w/o positive results...???


Argh....
