Excellent question. The best way would be to get to a shop that has experience with your model and will know if it is working correctly. Alternately you could find another owner nearby that can show you their car or try yours. A final way is to go over the whole car and make sure everything is as per spec. For instance check cylinder pressures, valve clearances, etc. Get a scanner and check the parameters to see what the car is actually doing and compare it against what the manual says. As for handling, the car should be light, no lost motion or play, and very responsive. Check the suspension for any loose, worn, missing, or broken parts. Check tire pressures, wear, and date codes. A good measure of the overall health of the car is watching your MPG and oil consumption.You are definitely correct....I am the limiting factor at this point in maximizing the cars performance. How might I determine if my car is performing as it should be though? I've never driven one before this, and don't know a way to compare it to what normal/perfect should be. Ideas?
