The car idles good but when you drive it on the road and it gets hot it cuts out real bad and loses power. We have changed spark plugs, wires, fuel filter, map senser and the injectors. We think its something simple but WHAT IS IT??? :(

You said it gets hot. Then why don't you try and fix that problem first? Bad water pump?

When I said it gets hot, I meant when it gets to NORMAL operating temp. It does not overheat.
So the problem is, it IDLES fine. But when you are driving and it gets to NORMAL operating TEMP. It cuts out and loses power. We think it could be a sensor but not sure which one. What do you think??? :cry: :cry:

Are you not getting any codes? The ignition module in the distributer could be bad.

The distributor is where all the spark plug wires come out. I is usually inside. It's a small black box with wires plugged into it.

I would get each cyl compression tested, See if you got anything wrong there, Also are u getting any kind of deposits on youre spark plugs?. Could have a bad coil.
