Car: 1995 Cavalier 1.8 Problem: as subject line. In neutral or in gear, extremely reluctant to rev past 3500, hesitant rather than misfiring, almost like a rev limiter. Bad when cold, gets better when warming up, not bad at all when full temp. Have changed fuel and air filters. Have checked for vacuum leaks and splits in the air hoses. Cold/hot air flap in air filter box works as it should (closes off cold air inlet when started from cold).
Not sure where the air temp sensor is - anyone? Would a faulty air temp sensor cause the above symptoms? There's no hint of anything wrong below
3500 rpm.
