maybe an oil problem now?
so truck starting running really bad idle very rough absolutely no power and tuner throwing icp codes. got to point turck would idle for a couple seconds and shut itself down. put in a new icp and still noting. i check the oil and was a little low. added 2 quarts started to run a little smoother added another quart smoothed out and sounded normal dorve it around the block all is great.
then went to town with it and couple miles into trip ran horrible again idle rough no power. got some oil dumped in and still running bad then as i got closer to home it evened out and sounded great pulled up to house put in parked and not a problem. possible oil leaking into engine and being burnt if so its happeing quick
only other think i can think of is return fuel line clog.
thanks in advance
