I replaced my TPS late last year due to some bucking issues I was having with the pickup. That seemed to help. Then a few monthes ago the surging, bucking came back. This time it started dying on me. The problem is always when I am at a stop. If I put it in neutral or park there is no bucking and zero stalling.

So a few weeks ago I replaced the IAC and the problems quit for about 5 days. Now the bucking, surging and stalling is back when it is idling in drive. There is also a metallic sound like a clicking that I can hear when it is idling. I am trying to figure out if this is a torque converter, transmission, or just a sensor issue.

I like to do my own work, but would also like to find a good shop in the Dallas, TX do you guys know of anyone in this area? FYI, I am close to downtown Dallas.

 

hate to say it... but i'd bet on TC.

 

So about how much are torque converters for this thing, and where can I find one.
