Need some advice

[MCFR22]

I'm thinking about trading my 05 F250 extended cab for an 05 F350 crew cab. While test driving the the F350 for the weekend I have noticed that the truck takes a long time to warm up and the heater just isnt what a ford heater should be. Prior to me picking it up the dealership replaced the feul injector modual and they also took off the K&N intake. they said the intake was messing with the mass air flow sensor and making it run to rich. Now when the truck sets at an idol the exhaust smells very strong like it is still running rich. Can anyone offer up any suggestions ot give me some things to look for?

I'm guessing you don't know what temp it actually warms up to.

You are correct. There are no aftermarket guages installed. I do know that it takes a lot longer than my truck and the heater does not work nearly as well.

Also sounds like it has an exhaust leak that was probably the problem instead of the K&N (which isn't good either), probably at the turbo or y-pipe. I would get the nose of the truck pointed into the wind and see if you still smell exhaust. You might also want to check the heater control valve to see that it's hooked up correctly and check the coolant level. Make sure the A/C isn't on recirculate air also.

Did they clean the map sensor before re-installation?

Couldn't it take the computer a little bit of driving to reestablish the correct program after the intake change?

Also could the exhaust have some gunk trapped up in there? Maybe you need to get it out on the highway and romp on it for a little while.

I put about 200 miles on it over the weekend including 80 mph highway time and also some 4x4 off roading. I'm pretty sure there isnt an exhaust leak. I'm smellin very strong exhaust from the tail pipe on an idol only. It has me thinkin about just keeping my truck but I do really like the crew cab F350. Oh and its for sale at a Chevy dealership so its like standing on the other teams sidelines.

Yikes! Well that blows my theory out of the water. What does "smellin very strong exhaust from the tail pipe" mean? Maybe your truck has a cat and this one doesn't? Maybe this truck is programmed and this one isn't.

you can buy my truck its for sale and it doesnt have any problems, lol. but i would prob walk away from that deal i would say a d-max mech shouldnt be working on a p-stroke, just my 2 cents

I agree with that. I would also have someone run a cylinder contribution test and see if you have an injector leaking. The long warm up is likely a failed Thermostat locked open.

Yeah scarey! I havent crawled under this thing yet to look for the cat. How can i find out if it has a programmer. It really doesnt seem to have any more power than my stock 250.
