COOLANT & PERFORMANCE TROUBLE! 2.0!

Asked by May 04, 2016 at 09:43 PM about the 2000 Pontiac Grand Am SE

Question type: Maintenance & Repair

Also was wondering if because of my dirty coolant
can it cause my Rpm gauge to jump as I slowly
accelerate? Or could this be another problem?  
With that said when I have to use power or "floor it"  
so to speak it goes quite well. Otherwise seems
that the motor runs great for it having such high
miles.  Ohh and are there any parts that I could
maybe take a look at or purchase to better prolong
the life of my engine?  Thanks for your help

Dirty coolant doesn't have anything to do with the RPM. RPM jumping during accelerating can be the transmission. Have a mechanic road test the car for you. To prolong the life of your engine, change the oil, and filters, speak plugs and change the coolant.
