running on 5 cylinders
 

ok im kinda new to supras but have i good mechanic back ground. i washed my 87 7mgte yesterday and now its missing a cylinder i checked all the plugs wires and coil packs what else could be the problem. it seems to idle fine just when im moving it seems like its missing. any replies would be great as this is my dd. thanks in advance.

There has to be more to this, have you done a compression test? Is there any smoke? How do you know he is missing firing a cylinder?

my old supra did this....

step one-get a compressor/hose/air gun
step two- open ur hood
step three- blow the water out of your plugs
step four- do a burn out and post it in this thread :bigthumb:

Did u just look at the plugs or did u see them sparking. I had plugs a few months old then went bad on me but the car idled fine till u gave some gas them miss fired like crazy. Car wouldnt even go 30 mph
