When i turn my car on it drives ok but after it gets to normal temp. and i turn my car off and then come back a few minutes later without letting my engine cool down enough i get a misfire on all 4cyls. but when i drive it for a few minutes it goes back to driving normal without the misfires but my CEL is still there. plugs are good pulled them out tonite and checked them. i thought it might of been the gasket between the engine block and intake manifold since the block is aluminum and the stock gaskets are metal and they run different temp. even re-checked to make sure every electrical connection is connected right and that there not shorting. also check my vaccuum hoses for any rip/tear. done a search and mostly found that the case are normally the coil packs gone bad but if anyone ever had this same problem or knows what i can do or check for i will appreciate it..... 26k miles on engine so far 05 STi
