First Dave’s Ditty:
Here’s one for the Mythbusters….Don’t park the nose of your car facing the wind in the winter. True or false? Well… true. Winter’s cold icy blast quickly cools or should I say freezes engine components, play’s havoc with your batteries charge and worse yet ( the real reason) drives snow and moisture up under the hood. This can cause damage to sensitive components. Automotively speaking …this myth is busted!
My 1995 Jeep Grand Cherokee has a tendency to stall out and sputter. I shut it off and wait for twenty minutes and then it’s OK. I have 365,000 kms now and drive mostly to the city, shopping and work. My husband “the mechanic” was supposed to fix this !
The fact that everything is OK after twenty mins leads me to suspect the fuel system. I would think that the fuel filter is plugged or that the gas tank has water / dirt in it. Foreign material will clog the fuel pump strainer. Don’t blame hubby too much “hockey is back in town”.
I have 2000 Dodge Caravan and for the last 2 months problems with the automatic transmission. I noticed that in the morning when the car is cold and I put the gear to D, nothing happens. The car will not move, it takes some time to get going. Later during the day when the car is warm, there is no problem at all. Will I have to rebuild the transmission? Are those automatic transmission treatments, that you can buy any good?
Unfortunately you are correct in your diagnosis. Shifter hesitation is a by-product of low internal pressure usually this translates to worn parts. According to Steve Joyce of Molyslip "there is no such thing as a mechanic in a can". Most additives are preventives, not curatives. Perform a full transmission service, add 2 tubes Molyslip ATS. This should help if the shuttle valves are sticking. Transmission overhauls of this nature are costly. .
