Engine runs rough?

My buddy has a code reader and I plugged it in tonight. It was the cam/timing. I cleared the code and the light went out. The wife says it's been running fine the last couple days. Maybe the restore built up on the sensor and caused a faulty code or something. No clue. We'll see what happens, but it seems to be alright now. Thanks for the reply/advice.

I had my oil changed, and it ran good for a couple of days. Then it started to run very rough (cutting back, hesitation, and low idling). The oill needle went to zero and my truck wouldn't hardly go. I checked the oil and it was empty, and smoke was coming out of the dipstick. Iput two quarts of oil in, but it didn't do any good. The next day I went to crank it and it was still running rough, and the oil needle still would not move.

If it's a 5.4L, you'll need 7-qts w/filter.
Check your oil drain plug and oil filter area for leaks.
Also check around your radiator area for leaks, sometimes there is an oil cooling eliment in or out of the radiator.

After started and went to leave truck ruff running. Went to town check engine light came on went to part store. Codes are P0301. P0316. P0171

I took truck to garage today they did a test and it was the coil pack in cylinder 1 running good now. They said must of threw all the other codes because of coil pack. Thanks for help

They took the coil pack off put on cyl 2 and it misfired. So put new one in for $40.00
