well this a screwed car,but i'm not giving up. here's the thing 3thru 6 (plugs) are fouling out with in about 300 miles. any clue in the ingition system that would allow such a problem would be some help,also how is the testing done on the ignitor and coil packs. yes my spelling sucks

hmm maybe timing is off? save this link Cygnus X1 - Supra it has the mk3 tsrm. i beleive it is for a 91 but most of the material is usable for all mk3's

i thought the same it is dead on

Are the other two just a little fouled out or not at all? If your fouling out plugs, I would imagine it's because you're getting too much fuel. If your getting too much fuel, something is telling your computer to deliver that extra fuel. A bad 02 sensor or ect sensor? Any codes?

a faulty o2 sensor will may cause the ecu to pull timing or like said above, increase fuel
