Thread: Stumped and have no access to a scaner

ok i lleft my scanner at home and went on vacation, now i have cel and my car is cutting out bad under a load. first #2 coil pack went out that fixed it. then i was driving and started cutting bad drives/idles fine just cant accelerate. any ideas what it could be? i already checked the firing order to make sure i didn't swap a plug wire. no shop around here has a scanner and oreillys doesn't offer one to use just to buy. worst case senario i buy another one. any advice will be greatly appreciated

Does the check engine light blink when you're accelerating? If you were having coil pack issues I almost wonder if you're having a connection issue there. My supercharger belt sliced through a wire once and it left just enough wire there that the plug would fire under no/ low loads but couldn't get enough current to fire under any kind of throttle application.

Yes it does. i checked my wires but i will re check again. everytime i accelarate and even stay in it ( cause sometimes it's not that bad ) the cel will blink

Autozone and Orielly's scan cars for free...are you sure you don't have a vacuum leak. Sounds like a "T" fitting is being blown off under boost. Check those.

No autozone here. Oriellys doesn't scan cars here either. I know if i was home it would be easier to deal with. as for a vaccum leak i will re-check, i will go over all of them

sprayed everything down with carb cleaner. No vac leaks. just put new plugs and wires on and it's not that either. any other suggestions?

I double checked the connection with the coil packs and there all getting fire. A lot of fire.

Now your kinda at the point I think where you need to know which code it is. Most of the time a flashing CEL is going to pull a P0300 which is just a random misfire. Could be a bad injector as well...

Take off the supercharger belt and see if you have that issue. You're getting a misfire under load which could indicate any number of things. I'm kind of curious about the state of your Ignition Control Module.

Here's a silly question, when you swapped coils, did you put a coil in with the same numbers? I've seen people swap coils and then plug the wires into the original coils which would now be wrong since the coils were swapped.

question i have for you is whats mods and what size pully do u have

ummm what do u mean? when u buy new coil packs, they're not even numbered, it doesn't matter which coil pack goes where...and you said they pluged the wires into the original coils soooooo huh?

Think he means some people get coil packs with the different numbers and instead of putting the wires where they should, they go by the numbers labeled on the coil packs. When I bought my GTP, the numbers where mixed up cause the previous owner must of got coils from a junkyard or something.
