general problems of the 1998 Chevrolet Malibu

I received my chev recall letter ref recall 14350 today. This is not a complaint, just info that may be important in reference to this safety recall. Problems I have had with my 1998 chev Malibu is : engine shuts off while traveling at highway speeds-sometimes engine won't start ( ignition key will not go all way to start position)-sometimes engine want shutoff (ignition key want turn back to off position). As a retired truck mechanic I know that the problem is in the ignition switch lock cylinder (tumblers are worn excessively causing the lock cylinder to jam and/or be come loose allowing ignition key to rotate off) . I have attempted to make repair myself but all parts outlets tell me that the lock cylinder is not available (must purchase $350. 00 ignition switch assembly) if this recall does not include replacing the lock cylinder,the problem will not be corrected. Experienced mech/tech can replace the lock cylinder in about 10 minutes.

1998 Chevrolet Malibu engine started racing at high speeds and the consumer was not able to stop the vehicle. The engine was still running on high speed until the consumer was able to turn off the vehicle. Tps sensor had to be replaced.
