Okay my problem is. First off I drive a money pit. most supra maniacs call it a supra. lol. I love my car. Its a 1987 supra turbo. I rebuild the motor about a year ago. It has lots of mods too much too list. But if anyone wants to know just ask. Anyway, the car just started to studder. I checked the coils its getting spark in every cylinder. Every now and then it will clear up and run right. I was aiming towards fuel so I sprayed some carb cleaner in my ic pipe. towards the tb. It cleared up for a while. Now its just studdering the whole time. I'm either not getting enough fuel pressure or my fp regulator is out. Is there any way to test the stock fp regulator? I really need help I have tried everything I can. sometimes it works. Also does anyone have a r154 for sale?
