I just got my new plugs(NGK Iridium IX TR51X) and wires(Taylor Thunder Volt 50:brock:) from Marylandspeed and decided to do a Sea Foam flush before I put em in since I don't have an oil catch can, yet(ordered one today).
The engine was warm from driving home from work. I pulled the fat vacuum line from the break booster, started the car, and it stumbled and died. So I loosely put the vacuum line back on, started the car, positioned my 1pt. can of Sea Foam near, and sucked down approx. 1/3 pint slowly. Probably over about 30 seconds. Half way through I put the vacuum line back on for a few seconds until the engine smoothed out, then sucked down the rest. I immediately shut off the engine, securely replaced the vacuum line, and waited 8-9 minutes. I know it calls for 5 minutes but i lost track of time checking oil, and scoping out the spark plugs and wires to see how hard/easy it would be. I started it back up and backed half-way out the garage preparing for a legendary smoke cloud. The engine started faster than usual, seemed like it turned over one time and fired. I immediately got a CEL. It sounded like it was running fine so I let it idle for a minute, and gave it a few revs. There was barely any smoke. I mean, it looked more like warm exhaust on a cool night that anything. I have Sea Foamed a car before(my old 300 awhp Talon, don't hate, I have a G8 now : )) so I have an idea of the color/quantity of smoke to expect. I drove it down to my local Auto Zone about 1 mile away, keeping it under 2000rpm and 20% throttle. It felt underpowered slightly even at this level.
It had 2 codes: P0106- MAF sensor condition, and P0303-Cylinder misfire detected cylinder 3.
My car is an 08 GT with 35,100 miles. Mods are x-pipe replacing center muffler/resonators and Vararam intake installed 300 miles ago(I freaking love this thing). Since the intake install(reset ecu for 2 hours) I have had no CEL or problems whatsoever except for not being able to control my right foot :popo:
I am hoping that everything is ok and it just needs an ecu reset to clear the code and it will be fine. I am guessing the underpowered feeling is because a CEL cuts timing or something like a limp mode. I have to drive to work tomorrow, 30 mile roundtrip....
So any ideas/thoughts? I appreciate it.
This could be a good reason to take it to the stealership. I think my LCA's are about shot, and I have a weird clunking sound(like 5-6 clunks in about 1 second) only on the first 1-2 shift(I always baby my car until it gets warm so this is always an easy shift at 1600rpm's or so) after sitting overnight.
As far as my mechanical knowledge, I consider myself a pretty decent mechanic with a decent amount of experience/knowledge. I rebuilt my talon engine after I melted a piston. Remember I said decent mechanic, not a decent tuner haha. I have changed a clutch in my old Ford truck, swapped an engine in a civic and a saturn. Swapped several turbos/manifolds on mitsubishis, starters, alternators, water pumps, etc....
Thanks,
Taylor
