Ranger Mods

Hi, first post.....
110K 2015 Everest and Ive been keeping an eye on these forums as to what might bite me in the future. Auto Trans was one in which I now have installed a PWR oil cooler, particularly owing 2.8 tonnes Cvan. Other thing of concern is the EGR cooler, although not leaking would like to maintain a clean inlet manifold in the hope to lower the risk of leakage. The other day I had the Intercoolers hose split (right on cue with the age), and replaced both hot and cold with Plazmans. While replaced I also removed the Throttle body and MAP housing to clean up to the EGR outlet nozzle. As expected there was about a 3mm build up of soot which was cleaned and as far as I could into the inlet manifold without removing. Any residual Soot down further to the cylinder head I was going to remove by a inlet manifold cleaner (liqui Moly) and there after perform once or twice annually as a routine Maintenance.
Questions
1) Does any one else have experience with doing this and there opinion Does it help?
2) when using the Decarb spray with the intercooler hose off through the throttle body the engine runs very rough (suspect very lean, being normally aspirated) and also at 2000 rpm when it can get there the Throttle valve is all but closed inhibiting the spray nozzle from actually entering the manifold. As there is now no cables where throttle adjustment could have been made, for those who had experience with this
a) how do you maintain a set rev range eg 2000 to 3000 rpm
b) did you have problems with pre-ignition while spraying (Knocks the shit out of the motor)
There are YouTubers with this and they show with the throttle wide open and engine not revving that high?????

I removed and clean my intake manifold at 90k.

I would never spray cleaner down the intake and flush all that build up through the engine.

Thanks Bala....
appreciate your opinion and keen to hears others. Taking the inlet manifold off requires the EGR valve to be removed which as you would know is a P$%#k of a job. I was hoping to just get away with the Throttle body and MAP housing, takes approx 2 hours. thus minimising the amount of crap through the engine to just he inlet manifold. Taking the rest off would be and all day job for me. Cheers

<no-name>,
Having the I/C hose off the throttle means the MAF can't measure airflow into the motor, so the motor has no idea how much air is going into it, and below 2500rpm the EGR is active and the throttle will be used to assist EGR. Combine these two things and I'm surprised the engine ran at all. The MAP sensor in the inlet manifold will at least tell the motor there is no boost.
Not sure what the best way to circumvent the throttle is. Maybe remove it? or connect all the inlet hoses and squeeze the spray tube into a hose join?
Diesel engines always run lean (100:1 thru 20:1), it's how they operate.

This channel has some good how to instructional content for the ranger. Worth watching if you have a few minutes.
