Engine Sputters & stumble.

sharter · #1 06-25-2005, 05:30 PM

Hello Fredjacksonsan. I have a new problem with my pickup now. When I 'm going down the highway and give it some gas, it wants to stumble like it is not getting the gas. It jerks and kind of sputters. I don't know if it is a gas problem or ignition problem. I've read the manual on changing the fuel filter and man is that a job. You have to lower the gas tank to get to the filter. I don't see why they made it that way. Anyway, Do you or anyone else out there have any suggestions on what I could do to check out?

Thanks for any suggestions to anyone!

sounds like your o2 sensors.

Well I just replaced the 02 senors about two weeks ago. This was before this problem ocurred. I changed them out to get better gas mileage and they were probably the originals that were in there.

Plugs, cap and rotor? How long since a tune up?

Throttle position sensor?

How about catalytic converters? If they're clogged they will restrict exhaust flow.

I've replaced the plugs & rotor about 2 months ago. As for the wires,cap,throttle sensor, & catalytic converter, no.

Thanks.

So the problem started after you changed the O2 sensors? I'd start there for sure. Make sure you've got the electical connections hooked up properly.

So if it is a problem with the 02 sensors then why did it run great after I installed them? It seems that it should have acted up right afterwards instead of waiting a few weeks.

If you've already tuned it up and it hasn't helped, you're intake gasket is probably blown. There is a new style gasket. Have someone ck the intake gasket. Seen a butt load of 'em.

Sorry, I forgot about the software update for spark knock and a bulletin to re-route the plug wires. This will usually correct the problem if it happens mostly going up hill or under heavy acceloration, most often around 45mph.

Yes it does do it mostly going up hill and upon accelleration and around 45 mph. I did replace the dist cap yesterday & have not had it on the open road yet to see if this corrected the problem. The old cap was in bad shape. I'm kind of trying to eliminate one at a time.

What do you mean by software update? The wires are in a bad location & the cap was in a place that made me cuss.

Thanks for the reply.

I believe he is referring to this TSB

Well my Dodge finally bit the dust today. I was driving to the store and it was sputtering and stumbling and I gave it the gas and when I stopped for a light it shut off and would not start again. I think now possibly the fuel pump could be the problem? Anyway I had to get it towed. For sure now I will find out what it was.
It acted as if it was out of gas and I had a half tank.

Just wanted to update this problem to everyone that has replied.

Thanks for the replies.

The catalytic converter has plugged.

sharter · #15 07-03-2005, 03:36 PM

What makes you think that the catalytic converter is plugged?

Thanks for the reply.
