help my 85 runs but when i push the gas it wants to cut out i have tuned it up checked the mass flow itis ok throttle sensor is new new egr and it still does this cut out when cold after ten minutes better but it seems to want to miss fire when running then jumps and purrs then falls back any ideas would help thanks bill

Put a fuel pressure gage on it and watch your pressure when it acts up
If so, have you checked the Harmonic balancer to make sure it has not begun to slip (this will move the timing mark, and make the setting procedure inaccurate).

When you replaced throttle position sensor did you do a check of .54 volts because it wont be .54 unless you set it. And do a minimum idle adjust.

Only an issue if he messed with turning the distributor.
Check the fuel pressure like mlm0 said.
starting with fuel pressure is your best bet...pull the vac line on your pressure regulator to check for evidence of fuel...have you ever changed the fuel filter?.....
to those who sent me notes i have checked all the above pressure guages adjusted tps to accured degrees the problem still exists there seem to be a electrical issue from the module burn panel no power to the mass flow as per manual somethinng about 5 volts to and from and maybe ecm any thoughts thanks bill 1985 stock
