1gtte running super rich, HELP!

[turmite]

5 years ago i put a 1ggte into an RA60 celica with alot of advice from the members on this site. Since then it has run like a dream until now! I Pulled the plugs today and the motor is running super rich. Ive lost a heap of grunt. I swapped the air flow meter with anouther unit I had in stock but no change . If anyone has any idea please help! Ps Ive consulted to mates whom are mechanics. 1 says either tempreture sensor(ECU) or air flow sensor, the second recons the fuel pressure reg and that the sensors dont make that much differance. Any help would be appreciated!

check that you haven't removed the vacuum line to the FPR - or not connected the TPS or CLT (coolant temp sensor) back up.

The sensors will make a difference.

Are you getting any error codes from the ECU?

Thanks for your reply but ive gone over all of that. Where would be the best place to try for replacement parts. I dont have the VIN as the motor came from a front cut ga70 supra. I know its alate 89 Gen 3 motor but local toyota shop doesnt want to know about it without the VIN. Is there any way I can test the FPR or the other sensors to give me a point to start? Ta for the help, this thing is really starting to tick me off lol.
