problems with coil #8 check engine light

[4VFTW]

Not sure who tuned it. I just got the car this way.
UPDATE: pulled the plug. Has oil on the threads and burnt oil on the tip something is going on. Just not sure what. Swapped coils 7 to 8. Doubt that's the problem.

no bueno

you just bought the car? like how recently and from who?

Sounds like a#8 for sure

Just bought the car from manheim auto auction. Was owned by Fred beans ford west Chester pa. Has factory warranty but I assume I'm screwed. I just don't understand how it runs so smooth with this problem. I'll be doing a compression test ASAP. God damn iphone needs a compression test app!!

After this is fixed what's my next move to keep this from happening again??

One step at a time. Do a compression test and report back with your findings

Post a picture of a couple plugs. You bought the car from an auto auction?

this & this.

taking the cai off & flashing the car back to stock & getting a bunch of drive cycles on it stock wouln't hurt either ;-)

How do I flash it back to stock without having the original tuner?

I don't know how to post pictures here. And yes I bought it at a car auction. Mannheim pennsylvania. It's the largest auto auction around

damn, you need to find someone willing to flash it back to the ford oem tune. on the down low. Probably why this was at the auction. Do you know anyone at a ford dealer? Also need to find the oem air box and intake

nope. im not getting in trouble. that is fraud. not worth losing a job for. should have done more research before bidding on the car.

Understood

I'll just build a new motor. One that will hold up.

I thought the dealer could tell if the car was flashed regardless of whether it was flashed back to stock or not?

They go by key cycles. If the ecm shows 20 cycles of the key but car has 30k miles on it, that would tell them it was recently flashed.

Right, I have heard that before. There wouldn't be any point in flashing back to stock then if that were the case...

 

[theACE]

Can you not just turn the thing on and off a $hit load of times then? Like 400 times?

 

[Dlic]

No compression test yet. I should be getting it soon had to order a tester.

Sounds like no matter what I do to put it back to stock if... There is a issue I'm screwed either way. If I wanted it fixed under warranty. After all these hoops like I said I'm better off building a new short block piston and rod kit.
