Six problems related to ignition have been reported for the 1999 Ford F-250. The most recently reported issues are listed below.
1999 f250 super duty 7. 3l diesel. Cps sensor failed and caused the engine to stall while driving 65 mph on freeway. There was no power steering or brakes. Vehicle very hard to control. I replaced the cps sensor(f7tz-12k073-a- synchronizer) and repaired the problem. Very similar to the thick film ignition issues from the past. The old part is available to the NHTSA.
1999 f250 with a v-10. Spark plugs have blown out twice and where repaired by dealer. Expensive! one of the repaired plugs blew out again. Had to have head removed and taken to a machine shop. I have contacted Ford on each occasion and they claim they never heard of this problem before. It ruins an expensive coil pack each time.
First we started to hear a ticking sound from engine. Dealer said it was something to do either with the fuel system or the y-collector on the exhaust. They advised to change y-collector with something less performance oriented, sounded incorrect so I obivously declined. Soon after while traveling down in baja mexico we were climbing a mello grade when bamm!!! we lost most of our power and it sounded as though we were riding a large lawn mower without a muffler. Since we were in mexico with no cell service, we crawled all the way home after midnight. Upon inspection, rear passanger spark plug had blown through the threads and took the coil with it. Replaced with cold-fusion coil, but still sounds as though main bearings aren't going to make it much longer!!!!.
While driving heard a big bang, lost engine power. Had vehcile serviced, spark plugs stripped into head of engine. This was a common problem. Contacted dealer.
While driving 20 mph consumer heard a loud bang under the hood. One of the spark plugs had blownout, causing 2000 dollars damage to vehicle. Jlg.
Cps(camp position sensor has failed on a 1999 Ford super duty 7. 3l psd a total of 3 times. First time, son and I were turning into a walmart parking lot, and vehicle shut down and refused to restart. 13k miles on it. Dealer fixed cps. Second time traveling down interstate 95, and suddenly vehicle shut down again, while doing 75 mph. Fortunately the truck is a manual transmission, or we would have ended up in the trees, or into the side of the semi that was passing on the left. Third time we were towing our travel trailer, and truck died on a 8% grade, there was no time to get out of the lane we were in to the shoulder before we slowed too much and caused a wreck behind us the truck now has 77k miles on it. We feel the cps failing 3x in 77k miles is exxx. . . The last two sensors were not under warranty and cost $250~ we have researched on the internet and found out that the cps is a very common problem, and has shown up in mileage instances ranging from 100 miles on odo. All the way to not showing up until 200k miles. We, (along with apparently thousands of other truck owners) feel that the vehicle shutting down, and losing 90% of our steering and likely 85% of brakes (on diesels you do not get a "reserve" brake boost, unlike on gas engines with vacuum), as the brake system is powered by the hydraulic pressure provided by the power steering pump!!!! we know there is no way around the brake system. However, in two of our cases. It was very scary and a very dangerous situation when the truck died. We now have a spare cps inside of the glove box inside of vehicle and proper tools to replace it ourselves should it happen again. We have heard of other people driving said trucks with 7. 3l psd engines ( do not know if the 6. 0l is having the same problem with the cps) of the trucks being totaled and people being seriously injured because of the cps failing. We feel that a recall, should be made. . . Thank you and good day. . . .
