Check Engine Light

On the 2000 mile round trip to Florida, on the way back, the check engine light came on while running down the interstate.

The car was running fine , no problems, smooths as a baby's A%$. We stopped in Rock Hill, SC to spend the night at our 1/2 way point. After calling around and getting 69 dollar and up quotes for someone to code read the car, I bought a code reader ( 199.00 , as I was going to buy one anyhow, just not on vacation LOL ).

It read the codes and said that there was a misfire on cylinder 1. The car was running great. I erased the code, took it on a 30 mile run that morning before loading up the family again. Drove it home from there ( 500 miles) and never got it again. Got 25.5 mpg going from there through the hills of WV doing 80 + most of the way. Nothing to complain about at all.

Talked to my dad , who had the same thing happen in his F-150 with a 4.6. The tech told him that sometimes it will pick up a single misfire or even just throw the code ( this was after the checked everything out).

Anyhow, the car is running wonderfully. Was wondering if anyone else has had this happen ? Something I should check ? That coil pack was replaced 10K miles ago ( when I bought the car and the dummies powerwashed the engine).
That reader is great, with the CD and that reader I should be good to go on the drivetrain.

Thanks in advance !
 
RE: Check Engine Light

I'm not the local expert on OBDII - but I believe that a misfire has to happen a couple of times before it fires off a "check engine".

It could be something that won't occur again - or something that requires a new plug or a wire. Wait for it to happen again.

I get a mid-winter EGR code - that only happens when the temp outside goes from above freezing to below zero in one evening (Lovely Michigan weather). I reset the computer in the Spring and nothing occurs. Never could figure out what happens - probably a bad gas cap or something.
 
RE: Check Engine Light

you can get a code reader cheaper than that. They have em for around $149 here and they used to offer a $20 rebate in addition to that. But they want 150$ to check the codes go figure lol!
 
RE: Check Engine Light

Thanks for the info , but I was on the road out of town and was pressed for time and was worried about what the code was.

Thanks..
 
RE: Check Engine Light

I see, well the only code that I got was the misfire on Cylinder 1.

Ill check again sometime this weekend.
