2001 CHEVROLET MALIBU

I have a 2001 chevey malibu it has 104000 plus miles it seems like every once in a while when I am traveling 65mph+ my car stalls. It feels like the brakes are being applied very slightly. And also when it does this if I have the cruise on it shuts of my cruise & I have to push the resume button! It does this only when I am going 65 + any anwsers to problem?

Could be a fuel pressure problem, check it and comeback with the readings

I have a very similar problem to the one posted. I have a 01 Chevy Malibu Ls with about 102,000 miles. Automatic trans, 3.1L. The same thing occurs to my car when I am traveling about 65mph with the cruise control. I just had the Fuel pump and fuel filter replaced with a GM fuel pump. It revs slightly at high speeds. I can noticably see the RPMs in third gear fluctuate slowly from 2,000 RPM to about 2,300 RPM. The Service Engine light came on briefly and the service code was given as a low fuel mixture on bank 1. I thought the replacing of the fuel pump would fix the problem but it didn't. The mechanic I took it to also sprayed some carb clean in the engine compartment while it was on to see if it would rev. It didn't. I assumed it would be an intake leak somewhere but I don't think that is a cause at this point anymore.

Sounds like the oxygen sensor didn't sniff the fuel enrichment because its already running lean-no need for correction

Better have bank no.1 check
