Hi -
I have a 2002 SportCross with 38K miles and over the last year or so,
both my wife and I have noticed an increasing problem.
After starting up and driving, the engine will seem to lag periodically -
the "mpg" meter jumps to 80, the rpm drops about 500, and it feels like
the engine dies - for about a second or two.
This happens irregularly.
It usually happens for a few miles then drives normally.
However, recently, after driving it 150 highway miles, then parking it in a
parking garage for 3 days, when we drove it again it was horrible.
We could barely get it out of the garage - it felt like it was going to stall.
Then it settled down, but by the time we got onto the highway again it
started 'lagging' again - but this time at 65mph. This continued for
over 10 miles, then stopped.
We've had our dealer try to diagnose the problem several times - they did a full
40K service, replaced an O2 sensor, updated the transmission programming,
and ran full electrical diagnostics.
Even though the Shop Foreman has (finally!) felt the problem for himself, they
can't seem to figure out what's causing this.
We're getting pretty *BLEEP*ed off, as well as concerned about driving the car anytime.
Does anyone out there have any ideas or similar experiences?
Thanks.
