help needed with my 2000 focus

[ptpdub]

specs are 2000 ford focus with 61000 miles on 2 ltr engine. car is in great shape, automatic and air-conditioning. brand new fuel pump. when driving the car around a long right hand turn, (off ramp kind of thing) the engine cuts out. like it shuts off but not quite off. when the turn ends, we are good to go again. next, the car wont rev high. like if you wanted to pass a car, it cuts out. I don't have a tach but my guess is 3500rpm ish. thats it. nothing higher, no matter what gear. I had a check engine light, and the code was a maf issue, I cleaned it off and cleared the code so now there has been no check engine light for a few days. this confuses me, I would expect a code but none are present. any insight you may have would be great. thankyou.

Based on my readings, most hesitations involve leak in the vac system. Proved it when I replaced my air filter one time and a housing bolt broke. After fix, the hesitation went away. Another is the spark plug. When I start to feel that it is loosing power, I would look at spark plug history and replace when it is due.

Sounds like a plug wire issue. The long exit ramp issue would lend credibility to forces pulling on the plug wires under continuous g-forces. This would also cause problems with the computer and your high rpm stalling.

Just a thought...
