I have a couple of problems I am looking for some guidance on. I have a 99 Dodge Ram 1500. It will start and when I start to drive and take my foot off of the gas it will die. It has a check engine light on that says the TPS is the problem. I have replaced the sensor twice. I have cleaned all of the grounds that I have been able to find. I also swapped out the computer. It is still showing that the TPS is the problem in the check engine light and is still dying. Also, I noticed that my passenger side headlight is good and bright but the driver side headlight is on but extremely dim. Can anybody provide some guidance on this? I am not sure as to the next steps that I should take. Thank you.

 

Have you tried cleaning the TB? The venturi that allow the AIS (auto idle speed) motor to work properly could be dirty and need cleaning. The headlight issue- have you swapped bulbs right to left to see if the problem moves as you move the bulbs?
