I have a 1994 Mazda B3000, ext cab, 120K miles, gutless in towing department. How can I improve the torque/hp, or what is required to drop a 4.0 Liter engine into truck? Please help

2001 Mazda B3000 Series P/U, F/C trouble, or Water in Gas by russ52

F/C stands for Fuel Control
 I have a 2001 Mazda B 3000 P/U truck, I filled it up 2 day's ago. It's now at slightly below 3/4 of a tank, (By the way, what size is the "Tank", 19.5 ????)
Today, 11 June 07 it started "Chugging Spitting Coughing every time the Engine gets up to & maybe slightly past "3000" RPM
 
 Is it "Water" in the Gas, or a Fuel Control (F/C) problem ?
Remember, every time it gets up to (or slightly past) 3000 RPM, it starts "Chugging Spitting & Coughing....
 
Please Help Me .....

What a piece of s**t!! I bought this thing on 20 Jun and traded it for a GMC Canyon the NEXT day. I am kicking myself for not test driving but was relying on the advice of my used to be best friend. Talk about underpowered, I traded in a 2000 Ford Ranger 4cyl, 16valves and it was sick. I had no idiot light on the dash so I didn't want to take it to the dealer for a "trial and pay" experience. This sick Ranger had more power. The Mazda had 12 valves, the minimum it takes to make a 6 cyl motor. This Mazda truck was special ordered by a dealer in Danville, Va from a dealer in Virginia Beach. Reason, the Danville dealer had not one truck on the lot. Not having enough sense to grasp why (the sales manager later told me that the reason they had none was they were too hard to sell!) Rather that babble on I close with "do not buy this truck. "

The engine in my truck automatically starts to race and then dies down to a standard idle. Can anyone tell me why this is happening?

We are also having the same problem with the same year make/model. We've had it fixed 3x and can't get it to stop revving. Truck has 51k on it. Sounds like the dumb thing is going to blow up. Suggestion was made that maybe it is a carbon buildup on the throttle body. Any other suggestions..

Found the problem. I purchased a Throttle Position Sensor located on the back side of the carberator. It cost me $36.99 at an automotive parts supply store. After replacing the old unit a friend used the truck for a week and logged nearly a thousand miles. No more problems!
