Missing, spitting, backfiring

Hello Chris,

This sounds like you have a timing issue. Check you crank angle and camshaft position sensors for correct signals, also check that the physical timing has not gone out.

Could also be a weak mixture, so check your fuel pressure & fuel flow. If the colours of the pre cat lambda sensor are white/white/black/grey then you can use the voltage output from the sensor to determine the state of the air/fuel ratio. The sensor works in the range of 150mV to 950mV (so 0.150 volt to 0.950 volt), when a weak fuel condition exists (lots of exhaust oxygen) the sensor will out put a low voltage. The sensor when on the correct exhaust conditions constantly switches high - low - high - low etc etc.... if low and staying low you have a weak fuel mixture. You can prove it by watching the sensor voltage and spraying some start fluid in to the intake, which will make the voltage rise. NB: be very careful (or don't do it) if you have back firing, as a back fire through the intake will ignite your start fluid!!!

98 Dodge Durango goes into gear but wont move?

How much transmission fluid did you put back in. If you didn't put enough it might not get the pressure it needs to change gears. If you put too much then it creates bubbles and foams and it will cause big problems as well. The 42/44RE transmission takes 12 pints (6 quarts) if the transmission was completely overhauled, torque converter was replaced or drained, and cooler was flushed. The 46RE takes the same amount. When adding transmission fluid you only bring it to the minimum level. After that you drive around and let it get warmed up for a while then when you check it, it should be at the max level.

If your A/C is blowing weak:

1st: make sure you have the fan up all the way, and you're A/C is on the MAX selection. If it's on Normal A/C it will blow lightly even with the fan up as far as it will go - however - if your heater blows strongly, but he A/C on MAX does not - you may need to replace the blower motor (usually installed on the passenger side, on the rear firewall, or under the dash on the passenger side (near heater core).

Also consider the fact that the engine has to work a little harder to operate the A/C pump, as it is having to cool the air faster (on normal); it is recommended that while driving, to run A/C on MAX as the A/C pump doesn't work as hard to cool the air - and does not use as much gas.

Please let me know if you need further assistance.

I have a 2003 dodge durango that is leaking power string fluid

They do make power steering leak stopper although I have never had much success with it. I don't quite understand what you mean coolant lines for power steering because that I know of on your vehicle I don't believe there is a cooler for your power steering.

Look at your fan. You either have a weak fan clutch or if its electric you have an electrical fan problem. You need to see if the fan is running strong when it overheats. I am assuming you have checked your coolant.
