Random Acceleration
After about a year I finally figured out this problem... so if any of you have this same issue hears what it is. This is a recall 799 requiring a reflash of the ecm. Here is the info... 1998 Model Year Ram (BR/BE) trucks equipped with a 5.9L Cummins 24 valve diesel engine ("6" in the 8th VIN position) built at the: The engine control module (ECM) on 30,000 of the listed vehicles may cause the engine speed to increase unexpectedly if an erroneous crank position sensor signal is received. To correct this condition, the ECM software must be updated (reflashed) NHTSA CAMPAIGN NUMBER: 98V209000 CHRYSLER/HIGH ENGINE IDLE SPEED THIS CREATES A SIGNAL WHICH IS MISINTERPRETED BY THE ENGINE CONTROL SOFTWARE, CAUSING A HIGH IDLE SPEED CONDITION. NHTSA Campaign Number: 98V209000 Manufacturer CHRYSLER CORPORATION Components ENGINE AND ENGINE COOLING Potential Number of Units Affected 30,747

Update, when viewing live data I found that my Actual throttle position is set at 12.5 which should be 0. And when it revs up, I do see it on my scanner. Does that mean the timbo is shot? It didn't last long if it is.

Ah I see. I don't have the dead pedal issue either. I still have full throttle response when I push the pedal. But, even tapping the pedal a bunch doesn't drop the rpms I have to shut it off for it to stop. It's very strange... I would think a code would show but nothing... I turned offf and returned the programming to stock on my chips and still no luck. Do you think it really is electrical and not mechanical ie sticking injectors?

No codes. Checked with blue driver and smarty. When I was viewing data live the throttle percentage would stay the same no spikes while driving, but of course it won't do it when I watching data live. As far as signs wire, do you mean the one to the tps?

Random Acceleration
Over the last 3 weeks, I've had an issue with my truck accelerating by it self. Not WOT like other posters experience but more like going from let's say 15% throttle position to 25%. At normal cruising speeds 35 or 60 on the free way it will happen a few times then stop. Other times I'll be going through a parking lot trying to find a spot and my truck will keep its rpms at 1500-1800 and I have to hold the breaks or shut off the truck and restart. I tried a apps reset eventhough I have timbos tps. Tried leaving the batteries disconnected for 24 hours. Tried running Lucas for injectors. Tried a known working tps(another persons truck with no reported issues tps) I have a new vp44 from thoroughbred with 6k on it. Timbos with about 28k. 7 x.0010 injectors about 35k Any ideas? My next thing I'm going to check is vacuum leaks.

Surging and Turbo Bark under heavy throttle
I may need to readjust the bost elbow then. I cant remember but I believe I just closed the port all the way and backed it a turn and it was right at 32. Might have came loose. And with my pump, I'll try increasing the pressure before I buy a new pump.

Surging and Turbo Bark under heavy throttle
It's the 17ss from goerend. Basically stock stall speed. To everyone's conclusion I need a new turbo. Basically trying to decide whether to sell some guns or just throw it on the plastic devil. I'll be doing the ground mod today to see if it helps any. It will be good to reduce some ac noise anyway. @Mopar1973Man so I was looking at how the previous owner set up the bd noise isolate. He snipped that wire and only left about an inch from the computer. Do I need to replace with a full length wire and reattach it somewhere?

Oh I see. I'll have to read more into that then. Most forums advise the super b special is great for 12v I assumed the Same for the 24v. I'm not too familiar with turbos. I do know when I was talking to Jon Dynamic. He was saying I needed a larger turbo just for the fact I had a triple disk tc.

Why is that in your opinion? I read that the benefits of the 14 is less turbo bark and more durability. Do the 12 blades spool faster?

Surging and Turbo Bark under heavy throttle
I was looking at the sxe 300 64.5/73/14 and was trying to figure the difference between the two. Seems like the the super b I might be paying for the name a little. Finding a inexpensive 64mm 14 blade is troubling. I found a super b special for the 03-07 would I be able to rig it to my 98.5?

Should I drop down to 1/2" lines instead? Or am I to the point I should get a 150 fass? Also back to boost and head studs. If I do get the super b special and waste gate at 37 psi should I be alright? I figure with the increased volume of air I wont need to run as much boost.

I run 18 in park 16 cruising and 13 at wot.

Surging and Turbo Bark under heavy throttle
I do a lot of trips to eastern Montana and a lot of the roads a 75mph so I need a bit more to end to pass. Also hauling wood through the hills is easier then when I was stock... i do wish my truck wasn't so loud though scares the deer miles away then I have to walk. So doing more testing with my original issue. I tried wot from 35 to 80 to see if it would do the same. TC locked at 70 no surging or bark and psi stayed at 32 for boost... My guess higher speeds less load during lock up. Is that correct? If so should I be flooring it to get on the freeway from now on to avoid the surging?

Ah ok. I will get everything done this weekend and report the news of my issues if anything it will be good preventative maintenance to keep that expensive vp44 healthy. I just switched all my accessories to the pdc noticed my gauges aren't fluctuating anymore. I'll have to get a larger turbo then to stop the surge for sure. Hopefully I can find a BD Special for cheap or anything equal in specs. Low 500's is the most I want for hp to the wheels.

Alright I'll have to give them a call. Thanks. For the w-t ground wire mod would I be getting rid of the bd noise isolate then? Also with all the accessories on the truck should I have an equal amount of leads/load to each battery or does it matter? (Accessorie Connections)
