91 P/U w/ 22RE runs rough???

Hi,



My '91, 2WD is fuel injected and has approx 130,000 miles on it. It misses during idle and "bogs down" thru accelleration but "catches" and takes off at times. Have changed fuel filter, air filter, plugs, cap and rotor. Wires only have a few thousand miles on them. Open to any suggestions.

Rob is my brother and I posted the original message over the holiday from his computer. I did take Rogers suggestion and tested the TPS and AFM. AFM tested fine. On the TPS I tested it closed and had to adjust it to get it within range. With throttle wide open I get an open line? Does run a little better on the lower end but still bogs thru middle third. I did not test other throttle positions with feeler guages. I'm suspecting defective TPS and contemplating replacing. Any suggestions. Thanks Roger.
