    Cool, I guess i thought that only 93-94 had EGR. So they stopped the EGR in 96?

    Anyway, thanks for all the great info!!!!!

    Get some vids going of how it sounds and how she drives.

    I took the 5.9 to a shop today to have it looked at on a Scope, turns out that the Bosch +4s SUCK, and that was my "slight miss" so I threw it Auto Light Double Platinums, and its smooth through acceleration.


    I also passed smog with a GUTTED CAT.


    LOL

    Now you tell me after I just installed them the night before I took it over to Scott. Oh well. Story of my life.

    Great to hear she is running smooth.

    ever heard of parallel circuits?

    Anyway, I run them in my stroker and so far they're looking good. The lifetime warranty is what sold me.

    Well my local Parts house returned my +4 and I went with some Double Platinum Autolights and its smoothed out.



    I have another set of Bosch +4s from the 5.2 anybody ?

    This person should be taken as seriously as a heart attack while piloting a zeppelin over a bacon factory, which is the most serious of heart attacks, because if that zeppelin crashes into that bacon factory all of us will be without bacon and that simply will not do.

    i also did the swap in my 94. As far as fuel goes, I just picked up a mopar performance computer and am running that. It has been running fine (as far as I can tell) since I did the swap either last year or the year before... cant remember when.. lol

    I did the swap in my 95 and added the Mopar computer as well. It pulls pretty strongly and the plugs aren't showing any sign of being run lean. The only hiccup was a little overheating on the freeway up long hills which was solved by a Hayden HD fan clutch.

    I went and ordered up an ECU from my local dealer, hopefully it'll be the answer to my problems.

    What problems? Mine runs stronger with the computer, but it ran fine with the stock computer still in it too.

    I've been having some problems with the computer stalling the engine, but my setup is a 5 speed. If you engine brake to a stop, and clutch in, the engine will stall. So I'm hoping that the Mopar ECU might be able to catch the engine from stalling a lil better.

    The Mopar ECU didn't do anything noticeable to fix the idle problem, the truck wanted to idle at around 200rpm, and would bring itself to a stall, we adjusted the idle adjustment screw to bump up the idle, and that seems to work fine. The truck would still stall out sometime, so we sprayed a ton of carb cleaner to clean the IAC, and that seems to have fixed things.
