Still no fix
Well the old Black Dodge is still doing the same ole thing. At light throttle in OD at 50-53 mph it will hesitate. It will do the same at 30 in 3rd gear. Drop into second or out of OD and problem goes away immediately as RPM increases.<br><br>So far I have <br>Repalced the APPS - $335<br>Sensor on OD unit - $30<br>MAP sensor - $155<br>Cleaned the IAT<br>Had it on comp. twice - $68.00<br><br>Im up to $588.00 and still no fix. When I do find it - I'll **** sure let yall know. :P

Re:Still no fix
Does your fueling box have the boost fooler hooked up to the map sensor? If so remove the boost fooler portion and hook it back up to stock. Remove the boost elbow/turnbuckle so boost levels will not exceed EOM specs. See if that cures you studdering. Leave the fuel box hooked up to the pump still. <br><br>I have been working on a simular problem as yours and wonder if the overboost is causing the pump to eratically defuel. <br><br>Just an Idea that I have not proven yet.

Re:Still no fix
Mac1 that accuatly makes sense ( well to me anyway ) To much air and not enough fuel? Your right at that point on the pedal that your flowing more air than fuel. You press the pedal and you get more fuel to go with more boost. Same if you let off of it, no fuel or air, it goes back to normal. I'm I making sense to anyone? My does the shuttering thing as well, its hard to tell unless I'm towing something.<br><br>My 2c<br>Kimrey

Sounds like an impending pump failure
I'm certainly no expert, but those symptoms sound sort of like what I had early on in my injection pump failure. Eventually, it just won't go under a load unless you basically floor it. Strange, but once it worked up a good head of steam, it would run OK. Problem was, I couldn't run around at 70 MPH everywhere I went!<br><br>Keep an eye on that, too.

<br><br>It is a good point though. If I stall my truck up at a light and punch it, it kinda surges a little. Sean's been with me when the truck's done it.

Re:Still no fix
Im not running any increased boost levels and oem boost is normal. Injection pump replaced 31,000 miles ago.
This problem didnt start till I was over 300,000 miles and its been doing it for over 6,000 miles.
When my first injection pump failed it gave no clues - just died like a cheap boat motor. Dead in the water!
If it is the pump - Ill run her till she's dead! ;D

Re:Still no fix
You know I thought about that. The CMP also plays a role in the cruise control operation (or so Ive heard). My cruise works when it wants to or I have to turn it on when i start the truck and will work as long as I dont turn it off.
But it looks like a real pain to get to. But thats my next thing to tackle.
Other than this minor problem. The truck still looks great and pulls like a team of draught horses.
