change fuel filter.then check fuel pressure.if you got TBI FUEL INJECTION PRESSURE SHOULD BE 26-32 PSI. IF YOU GOT MFI FUEL INJECTION PRESSURE SHOULD BE 40-47 PSI.if all is good .have car scan check the egr valve.map sensor. coolant sensor.if any one of those are bad it causes rich fuel mixture.that will cause you to fail smog test.also replace plugs and wires.if they are faulty they will misfire cause unburn fuel to come out exhaust.also check for for intake leaks check all vacuum hoses.

At WOT my 1990 3.1 euro won't up shift. Had it up to 8000 rpm-no shift. Just had tranny rebuilt with HD shift kit. Works and shifts great except at WOT. What creates the upshift signal to the tranny, what happened to the rev limiter? Thanx, Gary
