tar-like substance leak from the bottom of both the front and back doors on the drivers side of the vehicle.

This problem started out happening only occasionally then progresse. Have found that by turning off ignition and back on that the engine will run normally for awhile. This problem is sparatic sometimes in a 25 mile distance it can occour as many as 10 or more times, or not at all. Particular ly sensitivity to uphill.

I will then turn the engine off and wait 10 mins when I turn the car back on the AC works again for about 15 mins then blows warm air.

It will not stay running

I have an 1998 Isuzu Rodeo 3.2L 4WD. I recently replaced the radiator with a new one due to the old one splitting open along the top by the cap. I'm having problems where it wants to push the Anti-freeze out of the radiator into the overflow tank. I drive it with no known problems, I just can't go on long trips with out stopping to check it. It runs normal temp. I was told to bleed the air out of the system and i made numerous attempts at this, even put the front end up in the air and i get no bubbles coming out when bleeding it. I have hot air when i turn the heat on.

hold petal to floor rpms come up and runs good till you stop and start again boggs down

I have a 2002 Isuzu that started acting like it is flooded and the cooling fan does not come on. We replaced the fuel pressure regulator, that did not solve the problem.

What else can cause poor gas mileage OTHER than; low tire pressure, old fuel filter, old spark plugs, dirty air filter or and bad driving habits? All these things checkout but my truck still only getting about 16 miles a gallon.

Wanna add a 24oz. Lucas oil transmission additive to my tranny. The fluid level is good where its at. Do I need to drain some to make room for the bottle. Directions say "add to existing fluid". Worried about overfilling.

The part in question has a plastic piece on the hose that secures it. It is also located below the altenator.

other gears are fine... we had this problem before with our ford Taurus and it was due to a leak we sealed the leak but the car ultimately gave up on us anyway. how else can we fix a gear shifting issue? or is it most definitely the transmission?

I called around some said motor oil others said automatic transmission fluid. It look and smelled like gear oil came out of it.
