I remember when I finally did plugs and COPs... wow what a difference... but congrats on getting the ex back on the road

How much did you end up spending on the repair?

 

[omegalita]

I'm just waiting for my plugs and Coils (Accel) from summit. Hope i can fixit like you and enoying a smooth ride...

 

[Big Red Monster]

600 bucks..... but now the cel came BACK ON but its running fine. WHY!!! any one help?

 

[walnuts4x4]

need the code to help you out.... also did they reset the CEL?

 

[Big Red Monster]

well it was off when i got the truck back, it came on going home tonight, but again its running fine no misfireing or anything

 

[omegalita]

Perhaps an o2-Sensor? They don't love it to breathe unburned fuel...
But a code would be better....

 

[Big Red Monster]

ok got it scanned, sorry no code though but they said bank 1 and bank 2 are running lean. but the truck is running fine no shuttereing or hesitation and the light is off now. top it all off i did 0 to 70 in like 9 seconds, which is better then it was before tune up. should i worry about this if the light stays off?

Even with resetting the code there are times where the ECU is still processing bad info from before the repair. The fact that the cel went back off might mean that the ECU is starting to process the new info and is returning to normal operation. Sometimes this process can take anywhere between 50-100 miles or multiple drive cycles. I'd just keep an eye on things.

yea after he scanned it the light went off, but also before the tune up the battery cable was removed, so im guessing maybe the truck is learning the fuel and air mixture again, specally since this is the first time removing the cable since i installed my exhaust cai and throttle body spacer. im keeping an eye on it, so far its running good, like its brand new

 

[omegalita]

Problem solved also!

Changed all the 8 Coils and now it runs like new...

Hey Big Red did you notice any improvement with the tb spacer?

 

[Big Red Monster]

i noticed a little bit of a power gain on take off. also adds a cool sound when you step on the gas, my friend thinks I have a supercharger on it from the whistle it lets out lol, if your gonna do an intake might as well add a spacer, poweraid is the best

ok.....Im at a loss of words either my truck is possessed or its bipolar. yesterday morning the service engine soon light comes on. I looked at it said F*CK YOU! and kept driving. went to work, went out after work lights still on. going to take everyone home its still on, stop by walgreens shut it off come back out start it up light goes off and stayed off, trucks running fine and my mileage is up at 10.5 mpg. Any ideas as to why the light went off on its own. I had a po174 code about a week ago, could it be the computer was still glitchy from the tune up?
