I have 90K miles on my 04 Ranger with a 3.0 and have yet ANOTHER problem. When I am cruising at say 30 mph and the RPM's are only at like 1500 it starts to bog down you know exactly like your ran out of gas. Then I give it more and it starts going again. But at higher RPM's and WOT it feels normal.

Any Ideas?

Thanks,

Have you changed the fuel filter? I know I haven't and I'm at 103000.

 

Fuel filter was changed not even 15K miles ago

 

Try some sea foam

 

Sounds like you got a lemon fuel filter.

 

Thanks Mark I will try cleaning it with some MAF sensor stuff tomorrow and see if that helps.

 

No. I saw it somewhere and I thought it was funny.

 

I will agree with the other two on the fuel flter. When I bought my Focus, the first day I had it back on the road it ran fine for about a hundred miles then, out of the blue it would slowly bog, then shut off like it was out of gas. You could start it right back up, and be good for about 10 miles or so, then the same deal.

When I pulled off that filter it was full of all kinds of crap, changed it out and it was a whole new car. Then after that it seemed like about every 10 to 15 thousand miles, the same scenario would play out, there must have just been a ton of crap in the tank from somthing before I bought it. But just thought I would share.

 

Hell id flush that tank out a few times then.

 

I am going to clean the TB then check fuel filter.

 

I had a similar deal. It was one clogged injector. I am beginning to think that 100,000 is pretty much the time to pull the injectors and get them cleaned, or-ringed, etc. The issue with mine was always low rpm, nothing noticeable at hiway speeds. If I let it idle for 5-10 minutes the check engine light would start flashing.

 

Well yesterday I cleaned the MAF sensor and the IAC thing. Now my truck runs fine and does not bog down anymore.

 

Take your vacum lines off and pour some seafoam in. it will smoke like a banshee for a little while but ASE techs swear by it. Also try upgrading your fuel flter and have your fuel tank flushed out a few times. If that don't fix it pretty much nothing will other than having everything replaced or balanced/blueprinted to specs(which aint cheap).

 

Dude check the post above you. I use seafoam all the time too.

 

I knew you were not bull****ing and I know you know your stuff!
