1995 Ford Aerostar 3.0L Engine missses badly when cold, but seems to disappear when the engine is warmed up. Have replaced coil, plugs, wires, cap and rotor. What can be the problem?

The parts you replaced don't typically fail due to heat/cold cycles.You need to see if it might be the ignition coil.Make the coil easily accessable(take of the engine cover).Have a 12v test light and some sort of spark tester handy.Start the engine,let it run until it quits.See if you have spark at the coil.If not, unplug the low voltage connector on the coil,and put the test light across the connector,and crank the engine.The light should flash on and off.If it does,replace the ignition coil. If it doesn't flash,you may have a bad crank sensor,but this usually won't make it shut off,instead,it will cause it not to restart after heat soaking for a couple minutes.(I'm betting on the igniton coil).

Check this...




Hope this helps.

a faulty coolant temperature sensor could be at fault. if its telling the computer the engine is hot when its actually cold, it can cause performance problems. when the sensor tells the computer its cold, it richens the fuel mixture. once the car warms up, it leans the mixture out. if the mixture is too lean at startup, it will run poorly

how about ck,,coil,pick up coil, or modular,to see if u have an off voltage going to spark plugs

Might check the coolant sensor. Make sure it is reading correctly. If it is still reading cold on your coolant sensor it will tell the computer to run as if it were cold telling the computer to send more fuel when in fact it doesnt need any because the engine is already warmed up.

mass air flow, coolant temp. sensor possibly

Code#53: throttle position sensor high voltage. #85: canister purge failure. 36: (CSI) flow low or low revolutions per minute increase.

AM temp 55 car started but stalled out after starting. Attempted to restart and did not hear fuel pump. Tried again and then fuel pump kicked in. Checking fuel pump inertial switch and fuel pump electrical supply.

try changing distributor cap & coil
