Hey everyone.
I'm just checking with you guys before I go tearing into this truck to try and fix this horrible stuttering problem it's having. It's a '93 5.2 that keeps stuttering, even backfiring around the 2k rpm range. The only way to ensure that it won't do this is to accelerate fairly heavily. I already replaced the fuel filter and am about to check the egr valve and the coil. Is there anything else I should check? Thanks

Man, I am having the same problem right now. What the F*^$. I have replaced almost every sensor on here except the MAP and the whatever it is connected to the MAP by the fuel pressure test valve. New cap n rotor, and fuel pump as well. The only thing I have left is the injectors. It started to get real bad after I dumped a couple of cans of injector cleaner in it. After all these years of trouble free service its all going to crap.I hope someone has a suggestion.

Hey Simple....
Exactly which valves/sensors did you replace? Maybe we can figure this thing out. All I know is it's been slowly getting worse and replacing the coil(mallory hi po) a couple months ago made it SOOOO much worse. Hardly driveable. This thing has got me stumped.

SuperBee!
I have replaced both O2 sensors, TPS sensor, adj to .76VDC, IAT sensor, cleaned the idle speed selenoid, put new plugs, cap n rotor, and 180 tstat. I ported my throttle body and installed a flowmaster, and intense performance intake. I originally started all this because it was stuttering. It wound up being my fuel pump. I replaced that as well and it cured the problem completely. I ran awsome for a couple of months but was using an unbelievable amount of gas(1/4 tank for 50 miles)and started doing it again but on a minor scale. I poured two bottles of injector cleaner in it and after the tank was gone I added more gas. It started getting worse from there, quickly. I have checked for spark, good, The injectors are all reading 14.9 holmes, and getting a signal. My battery reads good as well. I do not get a code from the PCM, the light just comes on and stays on. I checked the belly pan gasket and it is clean. No excessive oil consumption.????? I will be ordering the Bosch FMS injectors next, if that doesn't solve it I am assed out for I have no dealer to take it to (I am in Sicily in the military) I will be returning to the states in May and will have to take it in then.

OK well today I just replaced the PCV valve in hopes that that might be an easy fix..well it's alittle better until the 2100-3000 range...then it gets bad again...tommorrow i replace the egr.. and Todd, if there was a leak in the intake maifold gasket wouldn't it porpoise at idle? It doesn't do that so could it still be that?

I did the PCV thing as well and no luck. Where is the EGR? I was under the impression the magnums didn't use em.

Are you talking about the pluger thing at the back of the throttle body. If you didnt change that or didnt clean it that can cause the problem.
I forget the exact word for it but it does the same thing as a EGR. It is facing the firewall. Simply unscrew it and pull out. There is a plunger. When you clean it dont twist it just spray and lightly wipe. you can damage it by twisting.
GoodLuck.
Simple and super i got a few friends that work as a mechanic at a dodge dealer I will get them to ask around.

The EGR valve is used on the magnum engines. It is the metallic round piece behind the throttle body on the passenger side with a little stem on it. I think this may actually be the cause of your problems. When the EGR fails the symptoms are generally rough idle, stalling, rough engine performance during light throttle, and stalling during deceleration. I would recomend replacing it rather than diagnosing because it's relatively cheap $32 and the diagnosis process is very complex. I'll let you know if this fixes my problems. If not, I've got some other things to check too.

I was reading some past posts and found out that the late 95 and up Daks do not have an EGR valve and did not find out what is used instead.

Thanks! Today it did something strange! I started it to warm it up, and as it was running it slowly started to make a sucking sound from the intake. It grew lowder and lowder and started to stall. I reved it a little and the sound went away. Once again WTF. It runs like it has a mild cam. Wab Wab Wab Wab, (got to love the sound effects huh).

Well I did manage to find something out. There are 2 versions of the "beer barrel" that were available. One had the EGR and one didn't. If you look at fast4x4.net he explains the differences. But I still don't know how to tell which one yo uhave other than looking on the passenger side behind the throttle body and actually looking for the valve.

I was always taught to check the timing first. If
it runs alright at idle its close but when it
advances it can be way out, causing
hesitation, poor economy and stalling and
even dieseling at shutdown...

Just fixed a problem that sounds exactly like this. I removed the fuel rail(you may have injectors in TB) and pulled the injectors. What looked like rust came out. I purged the rails and installed new injectors. Problem solved. It's funny how this happened right after I replaced my fuel pump.
Hope it helps.
Bye the way, $119 for a set of 8 injectors. I went for the 24# ones at $140.

www.ramairbox.com Check out this one. The pricing seems reasonable, but do not know about quality. Haven't tried it, but looks good. Mine is a homebrew, similar in design to this, with only one inlet at the TB housing that has a 'y'. It uses the same principles as old miners used to use for water pressure, (larger into smaller creates pressure) 2- 3 1/2 inlets into one just behind the grill, but in front of the radiator wraped in header wrap to keep it cool. I never liked the tubes with the filter on the end, air has to be sucked in. with this design, air is forced in and goes through the filter. Just more efficient, but not quite as flashy.

I think Todd W was right. As I have been surfing the other posts i find my symptoms to be leaning toward the belly pan gasket. I noticed one of my plugs was a little fouled so I took the TB off and noticed some oil in the pan. I have already ordered the gaskets and will see how it goes.
