Blinking Check Engine Light
Today I had a new anomaly with my car. Was at a local raceway, then lost a huge amount of power and 10mph off my trap speed. Immediately greeted by a flashing check engine light that would flash for no more than 15 seconds than disappear. Obviously I was losing power so I decided to limp the car home. I figured that it may be tune related since I got new ones or possibly bad gas causing a misfire. My SCT tuner wasn't able to pick up and DTC Codes either. Eventually I was able to plug in a 91 octane tune instead of a 93 tune which is what I suspected as a problem.
On the drive back I was being cautious, monitoring my A/F ratio and other aspects. Check engine never came back on until I decided to give it a little gas on a freeway on ramp. Instantly got a blinking CEL again. Rest of the drive home, no issues. Figure I will try to run some newer 93 with a fuel system cleaner/octane booster to see if it was gas related. Then if this doesn't work my only thoughts would be a bad coil or spark plug. I am just hoping I don't have a cylinder 8 issue looming or something bigger as I am sure the dealership won't warranty anything with my car. Anyone else experience something like this before. :Frustrated: |
Sounds like an air leak in the intake or charge piping letting unmetered air in
|
Hoping for the best for you. But yeah, you are right I think. A dealership will not touch your motor.
|
Sounds like spark plug to me.

Fu$k me. The light finally stayed on so I was able to read a DTC. I'm going to try a new spark plug tomorrow, but I'm thinking I am screwed on this one.

Damn that sucks. Hopefully it just needs a new spark plug and that's it.
How many miles you have on your 5.0? Total and since you went boost. |
Yeah, not what I was hoping to find out with the tuner.
13,5xx miles right now. Went boosted at the 12k mile point, been running the ProCharger canned tune up until last week which I had a dyno tune done. A/F ratios were not dangerous on either tune...May have to start reading into some warranties here soon. Tomorrow I will get it looked at if possible, don't want to go to a dealer right away since I know where that conversation will go. |
Damn that sucks. Hopefully it's just a plug.

Any smoke? Any water in the oil?

:facepalm: I hope it's a plug.
Ugh...$1k in parts plus labor...there goes my chances of affording a trailer. I just hope I can get this thing up before the Texas Mile. |

Haha, glad I can help you out here.
I would have to get the stock crank rebalanced though and the boss crank is designed to work with those rods/pistons. I would love to have a forged bottom end...but this situation this sucks. |
Just my personal opinion but if the motor is apart I would go ahead and put forged internals. There is no point in doing it twice.
