\"FordI have a 1990 Ford F250 7.5L v8 2WD. A few weeks ago I added oil(the correct kind) and the truck began to have a ticking sound from under the truck. And when I’m slowly accelerating at 35mph to 45mph there is a shudder from the entire truck. Also when I hit 70mph the truck runs terribly. I thought it was the U-Joints so I replaced those but they where not the cause. I individually pulled the spark plug wires off the distributor as the truck was idling and the tick was constant. The truck has plenty of transmission fluid(right color right smell) and is shifting properly. It is however running rich and it does not have the usual deep rumble when accelerating. The truck has 168000 miles.<\/p>\n

Ticking Sound<\/h3>\n

Sometimes a ticking sound can be from different things. It can be internal in the engine caused from lack of lubrication or worn parts. It can be external from a bearing on a tensioner or pulley. And can sometimes be from an electrical short from a plug or plug wire. Sometimes it can even be inside the distributor cap.<\/p>\n

Since your truck is also running rough and rich the ticking sound may be relevant.<\/p>\n

First of all if the check engine light is on or not check for any stored codes and post them below. The codes can be checked without a scan tool.<\/p>\n
