Hello members, I'm having (I believe) the same problemas many others. I have a 2004 TL 6mt w/161k, I live in Milwaukie, ORegon. I've been driving/working on cars since I was 16(now 28) and like to tink I'm pretty mechanically savvy. I bought this car 3 months ago w/159k. I'm unsure as to the timeline of ANY previous maintenance or if any has even been done.

-------
Car was driving fine Saturday morning, left a restaurant and felt some shaking and loss of power from the motor. Stopped at a light and gave the motor a light rev, totally felt misfire(s), also Check Engine Light began to blink.

I carefully limped the car home. Called a tow truck to take it to the dealer. While waiting for the tow truck I checked fluids ect and plugs and coils. Noticed the all three rear coil packs were loose, 2 and 3 were so loose(bolt backed out 3/4") that I could pull the coils out to the point where I could here the coil lose suction to the spark plug.

I disconnected positive battery terminal, tightened all bolts/coil packs and reconnected positive terminal. At that point the tow showed up. I hopped in and started the car with hopes that I had fixed it myself quickly. Started TL and the misfire was still present. I did not see/notice if the CEL came back on as I only started the car and revved it once to test.

I let the car go to the dealer. got a call later from the service manager, he asked me what had happened, I explained story, he said he thought they'd have to tear into it pretty heavily, wanted to start with $130 base to begin diagnosis. I asked what codes were present, he said "oh we havent even checked it out or started it up yet" !!! So how can he even begin to know what it is or how much it'll cost without even setting foot in the car yet? Dealers are Stealers.

Told them to check codes and get back to me. They called back with, if I remember correctly, 1,3,6 and random misfire codes. SM told me that one of my rear coils had burnt and melted to the spark plug and was unable to be removed. He wanted to remove heads, replace plugs, coils, have heads resurfaced and new gaskets everywhere to the tune of..... wait for it..... $4000. I put him on hold. Had to collect myself before answering him.

Told him that simply wasn't economically doable for me and that I'd have to have the car towed back to my home.

Since then, I've been doing all the research I can and I'm so thankful for this site.

SO I'm waiting to have the car returned to me so that I can start troubleshooting/replacing parts my self at my leisure.

I can't seem to get into the TSB for the misfires, I'm either "denied" entry or the info has disappeared.

If anyone can help I'd appreciate it.

BTW, day before the misfires started, I spent $1200 on Rota G-Forces. I desperately want to fix my car soon. I love this car and will do what ever necessary to fix it, even if I comes to a replacement motor.
