So my Ram 1500 is having a throttle/acceleration problems. Just recently, it won't accelerate smoothly. When I step on the gas, the RPMs rise, then stick, then rise, then stick. Does anyone know what could be causing this problem?

 

Welcome to DF.

Could be the TPS on the throttle body. Thats under $50 at O'Reillys or Advance, I'd try that first.

Otherwise, you may be looking at a transmission issue.

 

Ya, I just replaced the TPS, because the TCC kept locking and unlocking while driving, and I was hoping that would be a cheap fix for the problem. Now the engine won't accelerate smooth, and it has lost power since I bought it used a little over a year ago.

 

If the lock/unlocking problem is solved, but you're losing power/acceleration, you may have a failed catalytic converter, especially if its been getting worse over time. I'd take a look at that. If its glowing hot after a nice drive, time to get it replaced.

You can also get it checked at an exhaust shop. If you do need a new one, don't get a stock replacement. Get a Magnaflow high-flow unit.

 

I'll look into that. I was going to point to the exhaust next because when I do accelerate hard, there's a popping or backfire coming from the exhaust it sounds like. I put on straight pipes, and wanted to replace the cat eventually anyways. I do know it needs a new OD solenoid, because that completely shuts off on drives over 25 miles on the HW, I'm just hoping I don't need a new TCC too. Too costly.
