Was on the way to a friends house and my truck started acting up like jumping and stuff ....like it did back at thanksgiving wen I had to replace a coil pack ....well I went back home and hooked a computer-scanner up to it and no codes ....so I drove to o'rielly cause I figured it was tge fuel filter, so I spent $12 on tht ..... Got home (dad was not currently home) and couldnt get the original fuel filter off (truck is almost 10 years old) .... So I went to moms to use her car to get my gf off work and as I was goin down the road my service engine light came on so I figured it was another coil :/ im sad ....and I have to drive my brothers truck to school in the morning ....and u kno how it is NOT driving ur own vehicle ...

gonna hook it up to the computer-scanner after school tomorrow and hopefully I dont have to spend another $56 for a freakin coil pack !!!!

 

I hope you dont either. If you have luck like me it will be cylinder #4 or #8 which are the ones closest to the firewall lol

 

The last one tht fryed was #7 ....and it was saying #1 was misfiring so im hoping its tht coil and not something else ...oh.and atleast ill have a new fuel filter baha

 

I don't know much but last year I had a misfire in cylinder #4 usually after one misfire I was told another is common for some reason. Maybe just a coincidence but around 4 months later my engine light came back on....cylinder 6 and 7 this time. The coils are a pain with that. Like I said I don't know much I'm just sharing my experience. Sounds just like what happened when I got a misfire the second time.

 

Coil are common have you replaced the plugs recently just asking and when your pulling out the old coils are the dry how do they look

 

well the last coil that fryed was because (like a dummie) i washed my engine off with a high pressure nozzle :/ and it has water down in the hole that i blew out and made sure it was dry before i changed it out ....

 

Did you try drying the coil with a dryer

 

Replaced coil pack #8 and all is good .... But last time the #7 coil went out it gave these codes:
PO307
Cylinder #7 misfire detected
PO316
Misfire 1st 1000 Revolutions
PO351
Ignition Coil A ..primary/secondary circuit malfunction
PO301
Cylinder #1 misfire detected

 

Which light are you talking about? the service light is saying its time for service [oil & filter] if it wasnt reset at last servce it will come on early. just a thaught Bubbabud

 

"Service Engine Soon" light is the same as a "Check Engine Soon" ....but I was trying to see if anyone could tell me what a the codes meant besides the coil packs tht misfired lol
