Engine Performance problem
1998 Ford Ranger 4 cyl Two Wheel Drive Automatic 95000 miles
A little info first. I have replaced the following since I bought the truck with 70,000 miles a year ago.
- Plugs and wires - AC Delco 8 qty
- Air Charge Sensor
- Upper and lower O2 sensors
- PCV Valve
- Fuel injectors
- Fuel Filter
- Throttle Pos. Sensor
So here is whats happenening. In the morning I warm up the truck for 3 or 4 minutes while getting ready to leave. When I start to take off there is a little hesitation in power and a the enginge doesn't run its smothest for a second or two. When I get above 15 or 20 everything is great. Runs smooth no lack in power. Sometimes though when comiing to a complete stop the truck begins to lope and sputter, but only when I am at a complete stop. If I let off the break it stops or calms down. Even if I let off the break for just a second. The truck had died from this issue because I didn't let off the break soon enough or at all. The truck does have almost 100k miles on it. I am thinking Timing belt and maybe cat? What do you think?
