engine idles rough, severe misfire, new plugs, air filter, fuel filter. Will not tach above 2600 rpm's with the pedal to the floor, trans is shifting erradically, initially only missfired at high rpm-engine would make valve clatter noise and power was limited, within a week car now undrivable any suggestions out there?
 
There's no ses light on? You should have at least a misfire code, go get it scanned for codes!
