Transmission, Timing Belt... I'm getting frustrated.

Hey guys and gals...

Some background can be found here http://www.focusfanatics.com/forum/showthread.php?t=325318 (mods can combine if they wish... issues seem to be unrelated)

Recent work:

Plugs, Wires, Fuel Filter, O2 sensor (Downstream), IAC, Oil and Trans filter change and a new Catalytic Convertor, Coil pack. Also, power window regulator along with a new window... Yes, this is all recent and adding up.


After I eliminated the issue described in the linked thread, one problem remained... The car shift poorly when hot (40 miles) but tonight I got to drive it longer then usual and noticed the car drops rpms at slower tempos and you suddenly loose power.

So let me describe: Car runs fine till you drive 40 miles, car has issues shifting into 4th AND if you gun it (pass on highway),it will "lunge" (rpms jump up and down). Sometime a hard shift will happen and it will run fine or I will have to remove foot off the gas. Add to this is if I'm in cruise control (I'm not a heavy footed driver) and drive up a hill, it will do the same.

Car will start to have a "stumble" feel in top gear. Overtime, other gears will do the same and tonight I noticed the rpms dropping and a sudden power loss.

Any ideas would be wonderful. I know I need to get my timing belt changed and wonder if a stretched out belt could be the issue.

Not belt, car will run fine right up to the exact second the belt shucks.

Nice to know.

I'm going to give the coil pack a quick look in the morning. Been a few years since it was replaced and looking around the forums, some people have had the same symptoms (misfire on accell/ load on hills... my exhaust is also a little puffy).

Get it in bright daylight and look for cracks, they'll be small but you may have a bunch. Cracked coil=no bueno.

So....

The coil pack had issues. Replaced it... runs better.... then the car warms up and shifting issues reappear.

Its a hotter day today and it didn't take long for problems to appear.

But you said in the original post you had just put a new cat in.
Very confused.
