Hello I just bought a 94 camaro 3.4L V6 and was wondering if anyone can help me been driving it for a couple of days and drives fine except today on a freeway got to 70+ mph and noticed rpm won't go higher then 2000 even with my foot all the way down it don t move does anyone what could be causing this?

 

Probably a bad tach. Does the motor keep revving on past where the 2000 mark is but the tach doesn't go higher?

 

Ok so in park it does work goes high above 2000

 

So with your foot to the floor the car will not go much over 70 MPH?

There are several things that can cause a limited HP. Timing, lack of fuel or a plugged exhaust. Timing normally will cause other issues, the car will miss and jump, it could even back fire when reving it in the driveway. Lack of fuel can limit RPMs but the engine tends to get very unhappy as it starves for fuel. This would include bucking and missing at the higher RPMs. A plugged Cat or other exhaust restriction will cause the issue you described assuming you described it correctly..

 

Ok so car does go above 70 mph but hard to get even higher also just passed emissions do you think it could still be exhaust or cat? Also I think tho could be timing because I have been having misfire at low speed/rpm?

 

wonder if someone set a governor on it limitling the speed
