nice lookin ride!!!

the T-444E can definitely toss a ton of codes! the EBP device should only operate when the engine is cold.. if your thermostat is stuck open it could cause the engine to never make temperature until you have your foot to the floor climbing a hill where it warms up ebough to run in closed loop mode..

also if your ICP signal is failing then the IPR runs in a preset mode which gives you much less power than the rated on the engine.

your best bet is to Clear the codes then take the bus out for a drive and see which ones reappear.. only some codes will light up the WARN ENGINE light.

the injectors are operated via engine oil pressure (thus the IPR).. so first step is change the oil and get fresh in there to make sure you dont have a simple issue with dirty engine oil causing wonky oil pressure into the High Pressure Oil Pump and injectors..

I bought the bus from an individual who'd bought it from a dealer who bought it from an auction. It was in school bus service till earlier this year.

That's a good Idea, Christopher, about the oil I'll change it before I do anything else.

My wife did the computer painting. Didn't take her long. And yes it was a Cobb county bus. I see that you have one of them too, Sirdave. I'm heading out to get some oil and a filter now.

I actually looked at that bus when it was at the dealer and it got away before I could get it so I took the last one he had with 187,000 on the odometer. The dealer who bought them from Cobb county was right across the street from my house and I thought it must be fate and least that's how I tried to convince my wife to let me get it lol.

Echoing CadKid: keeping good, fresh oil in these engines is absolutely essential. Run a good synthetic. You'll thank me later. Doesnt really matter which one as long as it meets the specs.

The other thing both the DT466e and the T444 really appreciate is a little Power Service Diesel Kleen (grey bottle, not white) in the fuel. It helps keep the injectors clean and it reduces injector sticking. Cheap entertainment and you will definitely notice a difference. Works as a fuel stabilizer too, and with the bio-diesel blends around here, thats rather important since my bus tends to sit for months at a time.

Also check the trans fluid. It should be bright, cherry red and not smell burnt or like old gym socks. If in doubt, change it out andnreplace it with Transynd. Expensive, but so worth it if you will be pulling hills or are running heavy.

I habvenmt changed to transynd.. but I do know my 545's seem to run cool being they are in short busses.. thus far im still running dino oil in the 444E, im a bit skeptical on a synthetic as I feel my oil pressure is closer to the lower end of where i like it anyway.. on a hot day I typically run 38-43 PSI oil poressure at cruise RPM.. my DT-360 runs at 50.. so im concerned i'll lower the oil P by going to synthetic thinner oil..

I do indeed run diesel KLEEN in both busses.. in my opimnion they seem to run better.. at least it feels that way to me... I know the 444E seems quieter when I have diesel KLEEN in it.. I run a fairly high does.. 1/2 of a quart bottle to 25 gallon tank.. perhaps too much?

I havent yet tried the 2 cycle oil that others use in their fuel tanks..

I replaced the oil with rotella already. but I will try this kleen stuff when I drive it next and fill the tank. Gonna have to wait till tuesday to get it registered. I ordered a scangauge d which i hope will help me to learn something about the engine and diagnose problems. We got the seats out yesterday and the job today will be to figure out and hopefully get rid of all these switches on the doors and windows that make the buzzer buzz and keep the starter from working.
