Hello, My 1989 Raider 3.0 V6 has been running incredibly well. Though this evening I left my job and started up my raider, it ran fine as always. Drove to my GF house wait for her for 5 mins, truck was still idling well. As we left, i pulled into reverse and as I let go the gas the truck stalled out, Turned it on put in 1 st and left down the block came to a stop hit the clutch and at idle the truck stalled. I thought ok i might be out of gas, since my gas gauge is incredibly inaccurate. Though as I turn on the truck even with the clutch press or in neutral, the truck stalls at idling. Though when you press on the gas pedal the engine will run fine. I was able to pull on to the highway change into gears, down shift. Its only when my car sits at idle below a thousand rpm. Cause it usually idles around 600 to 500 rpm. I was wondering if it had to do with my previous repair that was made this week. I had a new Master/slave cylinder replaced, by a local mechanic.

I was thinking dirty fuel injectors, maybe some sea foam down the tank?
