Hey all, new problem this morning. Weather is foggy and damp truck started great drove for about 10 miles got gas. Went into a drive through and noticed that after the truck stopped there was a small clunk from the rear.

Like the tranny just came out of gear. Then when I went to start driving down the road the thing start to buck and when I pinned it it revved like crazy and shifted into 1st. It had a real hard time getting up to speed without giving it a ton of gas.

Let it sit for about 1 hour everything seems fine just drove it around the block.

Is this a moisture issue or a torque converter problem?

Hoping it's a moisture issue

Had it for about 3 weeks now and this is the first time anything like this has happened.

 

is sounds like its slipping into N when you floored it. is that correct?

 

No, just bucking with no power unless you just punch it. I thing it is a heat problem and a wet weather issue.

Started driving home from work and everything seemed ok until about 5 minutes later. The same issues still raining and it started bucking and no power. Put the truck in neutral and it Idled somewhat ok. Put it in gear and the idle started jumping and i though it might stall.

So I think maybe it is a engine issue more than a tranny or Cat problem.

Any help would be great would be nice if it stopped raining so I can see what happens in the dry. Note it has been working ok in the dry this is the first wet day I have driven it.

 

Ok just took it out again and ran ok for the first few minutes then it started again. Pretty sure not the tranny.

I have reset all the codes but still no help I do get P0152 O2 but that has been on for quite some time with not issues or is there different levels of failure?

Anyway since there is no distib. Any ideas on why. When I come to a stop it revves from 500 to 1000 and you can only get it running ok if you are above 3000 rpm's

 

it could be the TPS or IAC.

 

Can you clean a TPS I have done the IAC fair bit of carbon on it. Truck seems ok but I have not driven it far was working on the steering column.

By the sound of my post you would think I own a piece of crap but the truck cosmetically is mint.

I think my poor fuel is due to the bad O2 P0152 code.
ANd still working on the poor running when wet outside and the engine warms up.

 

the tps is cheap and easy to replace. id try that. just my $0.02 worth.

 

Well took the TPS off and it looked good gave it a couple of shots of cleaner. Drove it about 30 miles and it started again going to put new plugs in to see it that fixes the problem if not the I think I have no choice but to take it in and have it looked at DAM$$$$$.

Also got the lock - unlock thing now happening so it looks like a new CTM also. I see the the CTM does not have anything to do with running issues.

 

Well I put new plugs in but after about 20 minutes of driving it started again almost like it is flooding struggles to get to 2 grand absolutely no power until it starts getting above the 2000 mark.

Notice that went i unscrewed my gas cap there was a large suction sound. Could that be causing the engine to starve?

Also got a new engine code P0352 Ignition Coil B Primary/Secondary Circuit. I think it was caused by my #2 coil was left unplugged duuuu .

 

check fuel pressure.
