I have a '95 Dodge Ram, 5.9L, auto that idles fine, but as soon as I put it in gear the engine stutturs and bucks when I accelerate. The engine light did not go on. It's not the catalytic converter or the exhaust, I changed the plugs, wires and distributor cap/rotor, and the fuel pump/filter were replaced. Any ideas??? |

I would check for codes if you can. A scan tool would be great because you could see what your sensors are reading when it starts to act up. Does the exhaust smell rich? Was it acting up before replacing all the parts? If so that rules out wrong or incorrectly installed parts. good luck ETA: You might try a compression check as well. |

Its pre 98, so you can get the codes to flash to you through the check engine light. Get a haynes manual and it has the procedure. I have a 97. It could be o2. It could also be an intake plenum gasket. Has the oil burn changed since this has started happening? Get the book and check the codes. |
With my 01 cummins, you turn the key to "on" then "off" 3 times without starting. The codes flash on my odometer. It might be similiar for you. |

Intake plenum gasket. Take the air hat off the throttle body, and with the engine off, open the throttle body blades, and look down to the bottom of the intake manifold with a flashlight. See oil? betcha do. Make absolutely sure that you go to a Dodge dealer and get the steel gasket for the intake plenum plate. Anything else and you'll be doing it again in a few thousand miles. |
I think mine has a small leak, and when I take it off, that sucker is getting welded. No more gaskets. |
I had that problem with my '99 Durango 5.9. Pissed me off, because it occurred at 76k miles and I had a 75k mile warranty. The only problem it ever really caused was burning oil, and I ended up trading the truck at 110k miles or so. |
| My 98 dakota did something similar. Would buck and surge for 10 min then clear up. Was the crank trigger sensor. Firestone couldnt figure it out on 3 visits. (local dodge dealer service dept is incompetent to start with) and ended up having a dealer 40 miles away fix it. |
