Contour Enthusiasts Group Archives Forums General Troubleshooting Morning Hesitation...

In the morning when I first start the car, back out of my driveway and proceed to press the gas pedal, my car just, well, doesn't go anywhere, it just ever so slightly rolls as it would in idle. After doing this 2-3 times it picks up a little power and after about 25-35 seconds, its fine. This only happens after the car has not been driven all night and cools down. Its fine upon warm starts. What gives?

P.S. New O2 sensors w/ Cat recall
New Exhaust Gas pressure diff. sensor
Recently cleaned EGR
Plugs and wires have ~1K on them

Mine does it too. No big deal really since it doesn't last beyond the first time I accelerate.

Mine does this also. Same year (95) and engine (V6). It has the MTX. The odd thing with mine is that it is so temperature sensitive. For instance, it is usually fine on cold winter days, but first thing in the morning in spring or summer -- hesitation. I've replaced the O2 sensors, the EGR valve, and the Throttle Position Sensor. No change. I'm thinking MAF next.

I forgot to mention that I replaced the IAT also with no beneficial result.

Andy, have you had the cat recall done to your car? This started manifesting in mine after the recall and I'm trying to figure out if it is coincidence or not.

I did have the cat recall, but that was long before the problem started. What triggered my problem was cleaning out the EGR passages behind the throttle body. This was necessary to clear a 'Check Engine' light. I cleaned the throttle plate also -- I thought maybe I messed up the throttle position sensor, so that's why I replaced it -- to no avail. I almost wish the problem would get worse as it might be easier to diagnose.

Arent' there some seals on the throttle plate shaft? I read somewhere that cleaner will or can eat away these seals...

I've had this problem for about 20 years....Coffee works for me!
