To start with I have a 2001, F-250, 4x4, 6 speed manual, fairly stock truck. It does have a chip however as the 2nd owner of the truck and not the one who chipped it I honestly have no idea what kind it has. I purchased the truck 9 years ago and the previous owner just told me it had a 95hp chip in it. I added a 4 inch, turbo back, silverline dual exhaust on it after I purchased it and other than a K&N air filter in the air box the truck is stock. It has been fairly trouble free. I recently had to replace an oil pressure sensor to fix a lope it developed. The problem I am having started before the lope and has continued since the lope was fixed.
That being said the problem in which I am having is an intermittent problem that never seems to happen when it's been to a shop and the 3 different shops it has been at has been clueless as to the cause. There is no specific time or place that it happens however the same thing occurs when it does happen. Whether on the highway, on a back road at slower speeds or on 2 occasions even at idle the motor experiences what I can best describe as a hiccup. It is a sudden and at most lasting for a period of 2 seconds complete loss of power. The rpm gauge drops to 0 and the motor sounds as if you turn it off and turn it right back on. When it occurs there is a puff of smoke from the exhaust and it goes right back to running like normal. The biggest thing of all is that it does NOT throw a trouble code, there is NO check engine light activation when it happens. Does anyone have any ideas or experienced this same problem? Looking for any help I can possibly get please.
