Why is it that when I am going down the road (usually between fifty five and sixty five mph) my car will stall like it is going to shut off, but then suddenly, without losing any speed, it drives fine. It does not do this very often. It is already shifted long before it does this. So I do not think the transmission is an issue. Please help!

This sounds like a classic crankshaft angle sensor going bad, but to be sure lets run the codes.

The crankshaft sensor will not set a code but if there is something else going on we can see.

If no codes are present let swap out the crankshaft sensor to see what happens. this will give you an idea of what you are in for when doing the job.

Here is the location for your car both four and six cylinder locations just in case someone needs it.

Check out the diagrams (below).

Please run some tests and get back to us.
