Your description sounds more like a torque converter clutch problem. It would explain the poor mileage, having to floor it to go. I suggest having the transmission scanned, looking at the slip speed of the torque converter clutch.

Engine won't go over 5-10 MPH


You need to take the car to the dealer, because you need to recalibrate the electric throttle body with a TECH 2 Scanner, because the system went into a Limp mode.

Can I tow my 2002 grand caravan es on all 4 tires?


The answer is yes and no, but more no than yes. How far do you need to tow the vehicle? It is not recommended that any vehicle with automatic transmission be towed more than a few miles. With an auto transmission, towing without the engine running will not allow fluid to circulate throughout transmission, causing major damage to the gears in the transmission. If possible, use a tow dolly instead of towing on all four wheels.

What ring and pinion ratio should I use for my 2006 f150 4x4 with35x12.50x20 it currently has the stock 373s i want it to get okay fuel economy and still be able to tow a 5000 pound trailer as of now it...


I would leave the gear ratio you have in there. If you go to a 4:11:1 ratio you are going to be turning higher rpms which means more air/fuel mixture being burnt. If you go lower say 3:55:1 you will loose your pulling power.

Need to tow 1999 F250 about 150 miles home. What


If you have a stick shift, you rent a 2 wheel tow dolly and run the front tires onto it and strap it down. Put the truck in neutral and away you go.
If you have an Automatic you want all 4 wheels on a flatbed or tow trailer. You rent a car hauler trailer and piggyback the truck onto the trailer. A good rental will know the weight and rent you the right trailer.

Towing a 5x8 trailer with my Jimmy and now it won't start


Is your battery charged if so!!! I would look for the speed control box it is located under the glove box. It is a little white box with a lot of wires in it. this box is with the computer but there are separate box's. It controls everything from shifting to starting to the gauges in your dash You DO NOT have to replace the computer Good Luck

Car accelerates without pressing gas pedal


I had a similar problem with a K5 Blazer, where the gas pedal had a plastic pivot point in the linkage. After about 60K miles, the pivot developed a burr that locked the gas pedal open and kept the vehicle about 60 MPH. If I kicked the pedal to knock it off the burr, it would then slow down. Try it...
