dodge ram trouble

[2twin350s]

Man!!!!!

There isnt any thread on this site that can stay ON TOPIC.......

 

 

Hey Banshee barnes....

 

Common problem with those..

I wouldnt run the truck and spray carb cleaner thru the throttle as one guy suggested. It is too easy to flood the plugs out, hydrolock the engine, and saturate your oil with gas... and will not clean the TBI good enough.

 

Get a TBI gasket.

Remove the throttle body (they are very easy)

Get some carb cleaner, and clean the TBI assembly.Open the throttle plate, and get all carbon build up off the TBI and plate...Pay special attention to get all carbon ridges off the edges of the plate where it contacts the throttle body bore. The bore should also have no carbon on it where the throttle plate rides. You may have to use a old tooth brush and scrub the carbon off. Use carb cleaner that is safe for TBI systems.

Remove the IAC valve and clean the air passage of all carbon.

I would suggest a new IAC valve, but you can gently clean the plunger with carb cleaner.

Dont let any run down the pintle shaft.

 

Re-install everything with a new TBI gasket.

Disconnect the battery for 10 minutes.

Then start it up. If it stalls, keep it running with your gas pedal til it warms up.This will let the PCM relearn the idle rate.

Then shut it off, wait 30 seconds...cycle the key forward for 10 seconds, shut the key off for 30 seconds, then start it up.

It should idle good after that, and not stall anymore.

If it does keep stalling, you may have to replace the IAC valve..or have another problem.

 

 

The IAC valve islocated on the base of the TBI unit.

It is about 2 inches long, and 1 inch in diamter, held on with 2 torx screws. It has a cone type pintle valve on a shaft that moves in and out.

DO not Force that shaft with your hands.

 

If it is just carbon build up causing the stalling, the cleaning will only cost about 10 bucks with the gasket, and take 1 hour to do.

If you replace the IAC valve...Those are about 20-40 bucks.

Auto Zone, napa, ETC.... should have what you need.

b4 u go and do all that work^^^(not that hes wrong or anythin) when was the last time u changed the fuel filter

if that thing is clogged there is most likely ur problem

 

its prolly like a 25 part

[SinfulDragon]

if his 5.9 is like my 02 5.9 then there isn't a fuel filter. Its part of the fuel pump and he noted that he replaced that a while ago thinking it was the problem.

You can be all the Anti-FORD you want....... Who ISN'T fileing for bankrupcy?

Thats what I'm talking about. Ford is the only one thats not crying for money right now and when this is all said and done I think that the american people will realize that ford is the shit. I'm going to say the same thing I told my neighbor when he rode up on his new suzuki boulevard while I was washing my Harley Davidson Road King. Hey asked me how I could justify spending close to $20,000.00 for a Harley when I could of bought two suzukis for the same price. I turned around and told him that I would much rather ride the inovator then the imitator he just gave me a shitty look started his bike and rode away. Sorry I'm not trying to bash any one brand but I'm a home improvement contractor and I work my trucks hard and when we go riding I'm always pulling 4 to 5 quads behind me and I have owned both dodges and fords and ther aint one dodge in stock form that will out work, outpull or outhaul a ford period and anyone who works a truck will tell you the same thing. And I'm not talking about you guys that own a three quarter ton truck and all you do is drive it back and forth to work with a tie on to sit behind a desk or at most throw one quad in the back to head out riding. Thats not what I call working your truck. Just my .02.

yea i think in 94 thou they had the pumps and filters seperate

 

check the frame rails 2 c

i could always check shopkey when i get 2 work later but

Mine would drop idle a little at red lights. It was the EGR. Good to go now that I fixed it.

My old 94 had the pump/filter in the tank. No separate fuel filter.

ive had a 1994 dodge ram short box reg cab for over a year now. it is a automatic trans. with 4x4. the engine is a 5.9 or 360ci. its fuel injected. the truck itself has 228k miles on it. but in surprisingly good shape. the transmission was replaced at 130k.

when i bought the truck it had the problem....we put a new fuel pump in it ( it was going out) and we hoped this would solve it...but it didnt and i have been living with it for a year.

 

the problem: when i let off of the gas the rpm's dive down very low, and sometimes dies. i discovered when i rev the gas quick it goes back to idle smooth. at highway speeds the problem is not noticeable because you're going fast the engine doesn't go back to idle. i can live with it just having to rev it when going really slow. but for parallel parking i always think im going to hit a car. and due to the fact i have duel cherry bomb exhaust i look like a douche bag revving my engine every time i go slow in town (tight traffic).

 

what could be casuing the rpms to drop like that? but not do it when i let of the trottle fast.

 

any suggestions would be appreciated. thanks

 

Im not sure how that injection system is setup, but it may have a throttle position sensor going bad, or an IAC (idle air control) motor going bad. Im not sure it has a maf sensor, it may be a map vacume setup. Other thing to check is for vacume leaks, cracked hoses, leaking intake gaskets, etc.....

I forgot about this thread. my bad.

I did stop the problem. In a pretty redneck way. and im probly gunna get yelled at about it or something. I took some duct tape...folded it up to about 1/8 in thick and placed where the throttle cable hooks up to the throttle body i play. this made the truck idle higher at like 1500. at first. but after driving it a mile or so the idle came back down to around 700-750. and it doesnt dive down in the rpms when i let off the gas anymore.

This is a pretty redneck way of "fixing it" i know. college is starting back up and i'll have the truck parked alot. Im going to try what 2twin350s had suggested with replacing the tbi gasket.

and the fuel filter was replaced along with the pump.

 

 

BUT New problem has been coming up. the same thing happens with a cavalier i have... sometimes while driving it will feel like its starved of fuel and it cuts out. but then starts again. it did it when it was wet out and i hit a puddle in the road fast. What i think is that the ground wire for the fuel pump is coming loose... would that cause the pump to stop working? and if so....then why does it work again a few seconds/minutes later just fine?

[bansheebarnes]

I forgot to mention....i ran into the original owner of the truck one night. I was drunk lol. But i talked to him a while. from what he said this now would be the fourth fuel pump it's been through.

So...there has to be something causing it to be going out. I dont know many trucks that go though 4 fuel pumps. So what would be wrong that is causing this to happen? Idle drop....and bad fuel pumps. I do not run it low on gas. I try to take care of it.

[Dinner]

Could be some sort of restriction on the low pressure side of the pump. Whether that being in the draw straw/tank somewhere or maybe a hose/line? Usually gas engines don't go through fuel pumps too often. What kind of fuel pump are they, or are you replacing with OEM parts?
