My car has always had an issue with randomly shutting of during deceleration at low speeds. Normally approaching a turn or a red light. It's always been completely random and whenever it happens I've been able to start the car immediately afterwards. I always assumed that it was some sort of tuning issue. It was tuned before I bought it.
Well the problem, if it is the same problem, has gotten much worse. A few weeks ago I was cruising down the road around 55mph and the car died and it wouldn't start again. So I coasted off to the side of the road to figure out the issue. I saw nothing abnormal under the hood so I tried to start it again, it started, but it idled very rough. It would drop down to 200ish rpm and keep bouncing back up to 1000. Eventually it died again. After sitting for another 5 minutes or so I was able to start her just fine and the idle was steady again, as if nothing had ever happened. So I began driving again and everything went smoothly for about 15 minutes. I went to downshift and as I release the clutch the engine chocked pretty hard. I pushed the clutch in to let it coast/idle and it went back into the erratic idle. When I tried to give it gas it was almost unresponsive. I pulled off to the side of the road again and it basically did the exact same thing as 15 minutes prior. I tried driving it from my storage unit to my new garage yesterday, about a 20 mile drive, and the same thing happened twice during that drive.
The car has a KB boost-a-pump, which I'm not very familiar with. The dial is currently and has always been set to just over 10. I've never really messed with it because I don't want to cause the car to run too rich or too lean. When the car isn't shutting off on me it seems to drive more sluggish than it ever has. It definitely doesn't have that pullied cobra feel to it.
Unfortunately I haven't observed the fuel pressure gauge when all this happens because I'm normally in a panic that my car has just shut off in moving traffic. I started watching it while driving and noticed that when cruising it's at around 22psi and when accelerating it's around 25-30psi. I'm not totally sure what normal fuel pressure is for my car.
At this point I'm wondering if my fuel rail pressure sensor is going/has gone bad. Has anyone experienced any symptoms like this? Any help would be greatly appreciated.
