Sounds like you're on the right track. A bad TPS and ISC motor sensor will cause the problems you're experiencing. Your ECM relies on the readings it gets from the TPS to be sure there is enough air getting to the engine. If the ECM gets a bad reading and thinks not enough air is getting to the engine, it will cut the fuel supply, hence causing your engine to die. Your ISC relies on the reading from the TPS as well. It detects from the ECM if the throttle plate is closed or not. If it thinks the throttle plate is fully closed, it will start allowing air to enter the engine and bypass the throttle plate. If your ECM starts seeing some unmeasured air coming from ISC and detects the throttle plate is open (which it may not be due to a bad TPS reading), the ECM will again cut the fuel supply to avoid the risk of detonation.

So, replace your TPS first and see if that cures your problem. Also, check the resistence readings of your ISC to be sure that is within spec. If your problem still occurs, check your Intake Air Temperature (IAT) sensor in your air filter housing. Be sure your spark plugs, plug wires, and distributor are all in good shape as well. Replace your fuel filter if you haven't done so in the past 2-3 years.
Good luck!

My best guess is that you are are connecting to your AC receptacle with an extention cord that is too small. The Reddy Heater contains a computer that will shut the unit off if it cannot pull enough amps from your service. The longer the cord the higher the loss from receptacle to unit. This loss can be reduced by increasing the size of your extention cord. I run a 100' 10/2 cord.

Hope this helps!

SOURCE: 98 Escort Hard starting when hot

sounds like a dodgy mis reading of a sensor caused by electrical resistance which is turning choke on and flooding engine.know the fault but without car in front of me its difficult to diagnose,could be auto choke sensor which is on right hand side of cylinder head ,but not sure.best is probally dealer have you tried spark plug gaps ??25th although this would cause problems with cold starting not hot starting but its worth a look

1996 F250 powerstroke 7.3L keeps dying


It is sometimes difficult to determine exactly what is wrong with the 7.3L engines. Many times it is hit and miss for the do-it-yourselfer. It sounds like you are getting enough fuel at first and then fuel is being constricted. You might want to try changing the fuel filter. Sometimes debris becomes lodged in the fuel tank switching valve which would require cleaning the valve or replacing it.

93 ford f250 7.3 ltr diesal hard to start in cool or cold weather often run battery down have to recharge battery to start. new glow plugs installed 3 years ago. once started good for the day. warm weather...


This engine 'loves' glow plugs! One goes and the others try to handle the amps. Change them and you will have no probs! Other than that, I feel this is about the best diesel truck made!

06 Ford F250 won't start


Ford has a 100k powertrain warranty on their diesels... You can get it fixed at Ford if it's part of the powertrain...sounds like it is...
with a simple deductible payment of 100 bucks... well worth it.
