2000 Isuzu Rodeo - No check engine lights or warnings. Just recently it started to not accelerate when in D. It idles fine and doesn't feel rough at all. Also, there are no engine lights or warnings at all. However, when in D it feels limp and won't accelerate.

Also, at times when I put it in R it will stall as soon as I release the brake, but doesn't happen all the time, and if I pull forward, then it'll reverse just fine. It seems to stall when it's sat for a while in Park and you try to go in R first thing out of Park. Any ideas? I've been reading around and some say it might be the TPS (Throttle Position Sensor). It's about $70 at O'Reilly, but I don't want to spend that if it won't fix my problem.
