95 F250
Newbie here and hope someone could give me some help.
95 F250 5.0L Manual Transmission 210,000 miles.
The truck cranks and idles fine while driving until i hit fourth and five gears and then starts to idle rough and struggles worse going uphill.
I have replaced the TPS and AIC. MAP checks good. I have also replaced three broken exhaust bolts. I have replaced vaccum lines also and continue to look for leaks but nothing yet. Am i in the right ballpark here or is there somewhere else i need t0 be looking.
Thanks for any and all replies.

I sincerely hope you checked for codes before replacing those parts.

Next set of questions: When was the last time you did a tuneup with new cap/rotor/plugs/wires and filters? What is the fuel pressure at idle and with the vacuum line pulled off the FPR?
DTC 411 indicates that during Engine Running Self-Test, engine rpm could not be controlled within the Self-Test lower limit band.
Possible causes:
-- Improper idle air flow set.
-- Vacuum leaks.
-- Throttle linkage binding.
-- Throttle plates open.
-- Improper ignition timing (Distributor Ignition vehicles only).
-- IAC solenoid contamination.
-- IAC circuit short to ground.
-- Damaged IAC solenoid.
