Running Rough, bad injector?
I have a 2001 F-250 7.3l. Ive just noticed that it has started to run a little rough. Its running rough when idling then all the way up to the boost then feels fine, after shifting goes back to running rough. Worst past 40 mph truck starts to vibrate a little when pressing accelerator. Check engine light came on then turned off, hooked it up to 2 different code readers and nothing came up. no smoke coming out of the exhaust. I was thinking it could be a bad injector? Anyone had a similar problem?
