Sounds like my dramas ( except for the kickdown ) ive narrowed it down to a bad ISC and possibly a worn TPS

No kickdown and hard changing is caused by erratic or no signal from the automatic TPS (assuming its a 4spd)... if its a 3spd, check the condition of yer kickdown cable and replace or adjust it?

How do i check the TPS to see if it working !

Brent79

Hmm... 1 way without equiptment would be too swap the EFI and auto TPS wiring connectors. If your engine runs like shit but yer box works ok then its safe to say that particular TPS is faulty...
