Ok,

Here is the deal. the car runs great until warm- once warm it wants stall and idle very very bad at stop lights. I have to place in neutral and give gas to keep running. will start right back up after stall. No problem. I have replaced o2 sensor, IAC valve tonight, pcv hose, new plugs, new wires, new rotor, New rotor cap, New heads, Runs very good except idle at stop under load of gear. I have datalog from aldl No air system anymore, but I don't think that was it cause it just recently started doing this. I trace it back to filling it up with premium gas once a few weeks ago. Can't get it to run correct since. Can someone please help me by looking at my datalog.

oh ya, lo3 tbi 305.

 

anyone?

 

I'm also having a similar problem so i would like to know what you find. You should probably start by checking the fuel pressure.

 

sounds like the maf mass air flow that happend to me be4 and i changed it and i dint stall anymore.or i could be wrong?just tryin to help
