ok i have an 88 rx7 n/a and i garaged it a couple of months ago cuz i stoped a gas station and came back out and it wouldnt start no matter what i did so i gave up after awhile...now i really need the car to run so i start messin with it so i pulled the EFI fuse out and one spark plug that i could get loose and turned it over for awhile cuz someone told me that it was flooded. so i did that and put one new spark plug in and i got it to start!!! but barely and when it did start sh*t loads of whit smoke came out the exhaust and it over heated in like 3 min. after i drove it around the block and when i did drive it, it had NO power whats so ever like it would barely acelerate so brought it back and parked it and pulled the plug and it was full of gunk...anyone know whats wrong?
