Thank you, I will try it when I'm able to get home from work. It will be late tonight so expect something from me in the morning or early afternoon. Thank you so much for all your help...stay posted please.

Thank you for your response..tonight is another late night at work so I will try to get this done either late tonight or early in the morning. Thank you again for all your help with this. I especially enjoyed the video.....very nice bonneville in the pictures it'* sure a beauty. It gives christine hope.

I check the MAF and ran the car with it unplug. It ran a little better but what are some of the things I should be looking for other than the steadiness of the rpms? I plan to run the car to work in the morning with it unplugged and see what happens it'* about a ten minute commute with some challenging terrain. What are some of the things I should be mindful of? The throttle positioning sensor was changed by the stealership but I still plan to check it if I dont notice some change in the performance when the MAF is unplugged. When unplugged the MAF did not drop as before but I'm interested to see what it does tomorrow on the way to work....your thoughts?

If the TPS was installed wrong, it will cause problems. It needs to be installed a bit off set, and then turned in to place. When at rest the TPS will read just under 1 OHM.

Ok sorry for the delay I was dealing with some family issues....I got the EVAP code to clear with the new purge valve has not come back since....I looked over the engine again with a fresh pair of eyes and found a hose that was wrapped around the back on the intake manifold connecting to a sensor that was disconnected (stealerships quality work) I'm going to run it a little bit then check the TPS for ohm'*...thank you again for the help expect something this afternoon.

tested TPS reading at rest was 1.46 ohm raised to 4.56 pretty steady but the 1.46 is about .50 higher than normal would this cause the higher idling? And the sudden drop off under heavy load?

Yes it could. Something is keeping it from dropping down so the PCM thinks the throttle plate is in a higher place then it is.

As for the disconnected hose, sounds like the MAP sensor. And ya, that would cause problems. First, a vacuum leak, second, the PCM will get the wrong MAP readings and that will effect your AFR.

The sensor it was not attached too had a 1/2'' diameter hose running from the firewall into it and then the 1/8'' hose was disconnected. Don't know if that helps....could the TPS be dirty and need to be cleaned?

From what your saying, they connected the MAP to your climate control. Nice job there. The MAP is connected to the same place the FPR connects.

Nothing to clean on the TPS, it'* a simple potentiometer. It'* either seated right, or it'* not.

which one is the MAP sensor PED 14, PED 15, PED 16?
