TPS or more?
This may be a little long, but bear with me on this. 95 F150 with the 300 4.9L and 5 spd. Suddenly there is a stumble at part throttle. WOT and idle nothing wrong. Can sit at a light no problem and run the freeway at 70 like no tomorrow. I checked the TPS a few months back and it was ok. IAC is clean, new air filter, plugs are fine.
If I very gradually accelerate there is basically no issue, if I go a little deeper in the throttle it will kinda lag/stumble at about 20 in second and 40 in 4th. I am thinking the TPS is going and can't keep up with the throttle plates? Any other ideas?
