Hello,

Are there any differences between the 1990 2.2/2.5 liter TBI, injectors and the injectors used on the 1992 2.2/2.5 liter TBI injectors? I see some differences in the throttle bodies (fuel lines screw into the T/B and the throttle body temperture sensor is no longer used (front, driver's side, in front of throttle cables).

1990 parts book shows the injector w/o O-rings as P/N 4418924.
1992 parts book shows the injector w/o O-rings as P/N 4554101.

1990 should still be a 15 PSI injector, IIRC. Beginning in 1991 (except the convertible (AP), the fuel pressure incresed to 39 PSI. You can not interchange injectors with those fuel pressure differences.
