    Hi Brad Hogg, I want to help you with your problem, but I need more information from you. Can you please add details in the comment box? Please provide more symptoms and information. Is the engine light on? If the light is on then I need to know what the codes are. What is the mileage? Besides what you have recently replaced, were there any other recent repairs? What tests have you performed so far and what were the results? Do you notice anything with the oil pressure? Low oil pressure or a defective oil pressure sending unit could be suspected.

Monitor fuel pressure in the fuel rail and verify that it remains in spec. The fuel pump may be intermittent, which is a sign that it is failing. Could be a fuel pump relay issue as well (cheaper!).

If yours is the v6 2.5 the tps is adjustable and you can turn it up and down. On my mazda it acted like it was in the fuel system and i ended up replacing the distributor.

SOURCE: runs poorly(very Rich, stumbles) when map sensor

If it is fuel injected you may have a bad fuel pressure regulator. The regulator is attached to intake manifold with a vacuum hose and the bladder sometimes fails causing gas to be dumped directly into the intake manifold. Only solution is to replace the fuel pressure regulator.

I have a 02 Grand caravan that has new radiator, termostat, one new fan. the temp gauge goes up to max hot the drops right back down in seconds. what could be the problem?


it could be you have an air lock in the cooling system
remove the rad cap from the rad, start the engine and let it run until the coolant drops (add to fill it back up) or until the coolant boils out of the rad spout.

maybe pull the heat sensor. -replace it OR clean it off, reinstall it.

A blinking or flashing check engine light indicate misfiring. I suggest you check the components of your secondary ignition system especially if it worsens when it's damp.

Try to get it running a bit to warm up the exhaust. Take a point and shoot thermometer and take the temp of the cat. If temps exceed 400 degrees I would start to suspect a plugged cat.

It sounds like the plugs are bad or not heating correctly. Running it out of petrol can mess them up like that sometimes.

98 honda shutts off and will not start until cooled off


you say the engine shuts down when it gets hot if it runs rough before doing so it could be the coolant temperature sensor allowing the engine to  overfuel  if the engine cuts out in a couple of seconds but sounds smooth it could be the fuel pump , if it cuts out instantly its electrical.
