99 F250 V10 Sputtering

The truck starts up and runs fine. Then usually after a mile or so the engine feels like it is missing or cutting out. Sputtering usually inreases when going up a slight hill. Definitely not the transmission, it will sputter in park. Truck has had new plugs and fuel filter.

    For any interested. I had the diagnostic ran, and it was two ignition coils (coil on plug) malfunctioning. Not a cheap fix at all.

It takes just one of the coil on Plug units to cause sputtering and severe shaking. Fortunately the prices have dropped slightly for the coil units. The bad news is it is still close to 100 bucks from the Ford dealers. I have had to replace 3 of these on my 1999 F250 superduty V-10 since I bought it new. I believe there may be some compatible aftermarket units out there for high performance V-8 engines, but can not confirm compatibility.

I have a 1999 f250 Super Duty v10 that is only running on the passenger side cylinders and will not exceed 25 30 miles per hour


run the fault codes and look for ignition control module problems
v8 and v10 engines have a system where by every other cylinder fires when idling or for low power requirements but all are supposed to be running at revs

The fuel pressure sounds too low. Is it multi-port injection? Check the fuel pressure against your specs for the car and engine. MPFI systems usually require 40-50 psi.

What happens if you cut the catalytic converter off of a 99 ford f250 super duty v10 gas. will it run????


Good Evening, It is often that I hear this question by customers at work and I run down a brief list of what happens. If you cut or clean out your converter it will run, the exhaust will be a little louder and you will most likely get catalyst efficiency errors with oxygen sensor codes. And if you have emission testing you will most likely have problems with that as well. In short yes it can be done and yes it will still run. I hope this helps and if you have any more questions please feel free to ask.

I have a miss in my 2003 F250 super duty, replaced


I would say to replace the sensor and see if it helps. I assume you had the truck scanned and that was the only problem. The speed sensors usually relate to the ABS and Transmission shift points.

Both Autozone and Oreillys will scan for FREE. After you replace the sensor, get a water spray bottle and go around all the seams you can find on the engine while it is running. If the RPM changes you have found the vacuum leak that is causing the miss.

There is also another test that can be done electrically. It is the cylinder balance test. This directly relates to the compression of each cylinder.
While all the Diagnostics that showed the fault are accurate, the onboard computer does not tell everything.

Usually it can miss the mechanical issues like a vacuum leak, or a bad valve in a cylinder that is firing good electrically without the whole bank running rich with the unburned fuel from that one cylinder. This is because it averages the total burn rate for each bank.

On the V8 engines there are cavities below the Airhorn for EGR flow. If your V10 is similar you may want to look under the Airhorn gasket and clean the cavities. It should only cost your time and a gasket.

I have a 99 ford E350 15 pass van with the V10 gas engine with 120,000 miles and auto trans. The engine was missing at speeds above 45 MPH. I took it to a repair shop for a tune up. They changed the spark plugs and charged me $520.00. Well now it misses at idle to 55 MPH. They made it worst! I'll eat my losses and will not deal with the repair shop as they are giving me the run around. Can anyone help me before i get ripped off again. My last resort is the Ford dealer but they are the biggest rip off in the world.
Need help,
Harold

1995 Jeep grand cherokee is missing while running. When it is under a heavy load (driving fast) it runs fine. When idleing and slow driving it spits and sputters.


I have the same problem on my 95 grand cherokee laredo. Sometimes it starts out fine and after about 10 miles it starts spitting and sputtering. Then after a while it seems to clean out and run fine again for a little while. Then other times it starts out spitting and sputtering at the begining. I changed the fuel filter and that was not it. It is a 4.0L 6cyc. Any Ideas?

Thanks,
