1999 dodge Durango 5.2l V8 4x4
I have a 5.2l dodge Durango 99, it has 120k miles and already starting problems. When she's idling, she'll idle extremely low but wont die, don't know what would be causing that. Then I have another problem I've invested almost 600 into her. Everytime I get her around 45 mph she stars jerking and losing power while backfiring and shooting out sting fumes. But after 5ish miles she'll run correctly until I shut her off and her computer restarts. I've cleaned the spark plugs, heads, pre-cat 02, 02 sensors, spark plugs/ wires, throttle body, and map sensors. I'm fairly new to car (only been working on them for about 2ish years). Please help.

Have you considered a complete ignition tune? I have had similar issues with my wife's 99 Durango and when I took the distributor cap off, I found evidence of moisture. Replaced the cap and rotor while checking wires and all was well.

And clean the throttle body. Take it off the engine to clean it.... Pay special attention to the IAC well.

I guess you meant removing of idle speed motor, not throttle body?

Truck
I recently removed the throttle body and cleaned everything on it, took special care around the components. It fixed the randomly dying when I slow down but still chugs.
I'll give a better description on the problem, As im driving maybe around 20-50mph it starts to somewhat jerks/hesitate. As if its dying from no gas. You can pump it and it'll accelerate but go down quickly while jerking But if you remain the same amount of pressure on the gas it'll eventually go through the course and backfire. I was thinking the gas line could be leaking causing it to get too much air and not enough gas. The rotor on the distributor could be lose. A crankshaft could be jamming. When it starts to chug/hesitate/backfire It feels like not all the fumes are exiting the exhaust, then when it backfire it seems to clean itself up. I also get this horrible smell when it's chugging. Please help. Sincerely, Chevy |
Getting any codes? And pending codes? (Need a scanner to get those, parts store scan tool should be adequate.) Sounds like a misfire issue. have you done the tune up yet?

Codes
These are the recent codes I've received in the past few weeks,
PO443 EVAP Purge solenoid circuit PO141 02 Sensor 1/2 heater performance Dodge (ABS 65) Open Power Relay Contacts Dodge (ABS 45) Open Iso Solenoid Or Shorted ECU output LF P1594 Battery Voltage High Don't know if any of those codes could cause a misfire, but I'm not that experienced on vehicles yet. |
