2000 Dodge Dakota
3.9L V6 – 108,000 miles
Parts already replaced:
Distributor cap and rotor
Throttle position sensor
Transmission fluid and filter (dropped pan, NOT a flush)
*This problem occurred BEFORE the parts above were replaced.*
The truck will lose power when pulling out of a driveway or parking lot. Everything will be normal – the idle, starting, etc. It has never had an idiot light on. Highway and normal street driving is fine, this problem only occurs from an ignition off – starting position.
When it happens, I start the truck and put it in drive. When pulling out I don’t feel any resistance, just a loss of power (about half) and opening the throttle more doesn’t help. The only thing I can do is let it get over the problem (which takes about 10-30 seconds) and it is fine.
The most recent time it happened, instead of letting off the gas like usual, I kept a constant throttle pressure. There were two clunks under the hood that I suspect would have kept clunking had I not pulled off the gas entirely. After letting the problem resolve itself, I was able to drive normally.
The transmission did not have any metal shavings in it, but the fluid was very well oxidized. I replaced the fluid with O’ Reilly’s ATF +4. The magnet was coated with a greyish-black goo – I’m guessing wear particles from friction surfaces.
This problem occurs sporadically. I would estimate that 1 in 10 takeoffs have this problem. It can happen when the truck is warm or cold, but always from a resting, ignition off position.
