1995 ford f150 6cyl - runs rough when cold. Then

SOURCE: rough idle

Check or replace the EGR

SOURCE: dash board light came on, says ETC PWR?

"ETC PWR" means the "power mode" switch on the tranny is on. this lets the tranny rev above 3000 RPM, and is normal. look for a button near the center console and punch it. as for running rough, have someone check to make sure a coule of wires didn't get switched. also, you shoulda changed the plugs, too.

First thing you need to know is which cylinders are missing. Then, don't forget there is an engine beneath the electronics. Do a quick test with a vacuum gauge and do a compression test. Check the distributor shaft for side play. If everything checks out good, then do electronic component testing. have a code check run (many parts stores do this free) and get a chiltons or haynes manual and follow test procedures in there.
I refrain from giving repair suggestions with problems like yours because people keep changing instead of testing parts. When I work on my vehicles or other peoples cars, I do testing to avoid buying expensive parts that most times won't correct the problem. At this point the most I'd suggest is to clean the mass air flow sensor wires with a Q-tip and carb cleaner...that often helps and is free. If you run into a problem with whatever you find, ask and I'll try to help.
good luck

Testimonial: "I followed suggestions, it did helped some what."
