REDUX 1.
Why in the world post an engine and NO car told, yes 2002
DEAD WRONG IT HAS BOTH.!! VIN F TOO.

the CMP and CPK sensors both must be good and cam actually turns and cam timing in spec or the ECU cuts spark then cuts fuel..



cmp goes to icm and icm to pcm.2002 Ecotec 2.2 DOHC. no VIN F IS 2.4L AND VASTLY DIFFER\ENT

THIS IS THE 2.2L NOT 2.4L SO NOW i HAVE BOTH PRESENTED

Be careful, could be dangerous, and similar to the Toyota problems before. Gas pedal and or linkage sticking? Last time serviced?

yes 4,000 rpm is the limit. it is called the red line. actually it is 3,500

the computer is going to shut fuel to protect the engine thus limiting rpm, if there are no other problems with idle or throttle what its doing apears to be normal.

Neutral or Drive N rev limiter to prevent engine damage from no load over acceleration. D: many things could be at fault. Has your fuel filter been changed in the last 30,000miles. What about a tune up? Is your CEL(Check Engine Light) on? If so have a parts store check for codes, some do it for free. Then get back to us and we can go from there.

The engine is equiped with a rev limiter to prevent premature engine failure.

It's designed that why,so you don't damage it. It cuts off at around 3300 to 3500 in park and you say neutral.

if this is happening in park or neutral that is normal its called a rev limiter

Is it in park or neutral? I noticed the same thing on mine and realized that there is a rev limiter on the 02 3.8v6 that will not allow it to go over 4000rpm.

vacuum leak or idle vale problem
