On my 91 Q45 I had non-working TCS (Error code 19, TCS actuator) (totaled before fixing:cry: ) but yet my the throttle motor was unpainted aluminum and on my current car the Throttle motor is Black Why is that?

I ask because I want to put a 91 Throttle body on my 93 will it work?

Yeah... ppastos... look in your FAST!!!

In all seriousness, with the stuff you're doing with the part-outs, it would be good to learn how to proficently use the maze that is FAST since it will tell you a lot of these things. It's a big download at http://www.phatg20.net, but it would be worth the time.

I just need a straight answer because I am going to do the spark plugs and since the TB has to come off I will replace it to see if the new one (1991 Q45 base with TCS) works or not.

1991-1993 Q45 throttle body motors for traction control are the SAME, Just that 1993 had a different color than the 1991-1992.

I am guessing the internal were improved?

Wonder if 1994-1995(6?) can use the old colored motor to make the engines hard to identify. The only difference I noticed was the plug length for the 1991-1993 Q45 TCS motors and the 1994-1996 Q45 TCS motors.

It wouldn't surprise me if the color diffierence is completely insignificant - something like changing vendors...
