Cars lacking low end power

car lacks low end power…

car dosn’t pull strong until past 4000 or 4500 rpms

its a 91

i test drove an 89 and it seems to pull stronger any sugestions??

timing :roll: .
anything less then 20 degree will seriously hurt your low end power.

intake leak
that will also make your car run so rich that you will also loose low end power .

89 have a SOHC , more torque that the DOHC .
you will alwways have more low end with the 89 and more top with the 91+

Check for any exhaust or manifold leaks, it hinders performance when there is a leak. Happened to me a while back.
