First off I have a 1997 1500 with the 5.2. 191100 all original miles. For about 2 months or so when my truch has been sitting all night or is just "cold" and hasn't been run that day I will go out and start it up and about 2 minutes after running it starts to sputter and shake very badly. Like it wants to stall. This morning it started doing it real bad and I could smell bad oil burning. It was like hissing. I seriously thought it was going to blow up. Whenever I hit the gas though it stops and idles perfect and runs great when I start driving. What could this be? TPS? Thanks for any input.

 

could be your tps or iac, pull the throttle body off and give it a good cleaning.

 

02 sensor.

Im gonna get a new 02 sensor and a magnaflow hi flow cat and a new tps and iac sensors. see if this stuff does the trick.

 

The oxygen sensor is about 99% sure to fix it. What you've described is about half of the most commonly reported symptom picture. The other half is hearing the throttle body sucking wind.

 

Alright thanks man. so should i just replace it or get a hi flow cat as well?
