Sputtering idle
Hey guys,
So my 5.9 just made a trip from SF to LA so it seems to get the job done. Problem is, the check engine is on and the code is 233, engine power derate or engine may die....
The two mechanics I took it to said it's probably the fuel injector due to a sputtering that is very noticeable. Quite costly to replace.
My question is, has anyone ever dealt with this, it seems to drive fine, gets the same mileage, shifts ok, but when I'm coasting to a light or stop sign it put put putters and then gets into a normal idle once I am almost fully stopped.
Had one mechanic say it could fine for a long time, not sure if their are things I can do like cleaning the injectors etc?
Anyone got any ideas?

maybe take look around wiring harnesses for the ICP sensor, and IPR valve. might luck out and just have a short and could order new pigtail to solder in. or even replave the ICP sensor , see if it goes away, if not replace the IPR valve itself? cost for both parts ~ 300$ and you'd be able to do yourself.
what do i know though...

Isn't a '98 a mechanical engine? I would start with simple stuff first. Drain fuel from bottom of the tank to make sure you have no water. Change fuel filter. Use a lubricating fuel additive. I use Wally World 2 stroke oil. I am not telling you to use it. It's your choice if you want to or not. A gallon is less than 13 bucks. I would dump the whole gallon with a full tank. That's where I would start.

You could also get some silver Power Service to run through it.

try some mechanic in a bottle diesel cleaner for the injectors. its orange. i run cheap trans fluid in my dodge mechanical 12v have for 6 years. cheaper than lucas fuel injector cleaner. old diesel engines and new diesel fuel = long term problems if you dont lube your fuel.

If he's got a code it has to be a 24v. Code 233 usually indicates a bad injection pump. Could also be other things but I've only seen bad pumps cause it.
