Ok I have 2 very large problems here..

1. When i reach around 90MPH my car becomes impossible to handle even in a straight away I begin to Sway and can bearly keep it in the road. Right now the suspension is bone stock. Im just wandering if its because of the Old suspension. Or if it would be a bent frame? how can i tell if my frames bent?

2. I get major power Surges in my car.. Something gotta be wrong here. Its like im always running on lower HP than i should and then all of a sudden my car turns into a race car and the **** will easily spin in 3 gears and well it just flys its atleast a 50HP boost. But ive got no clue why.. Ive heard that maybe fuel injectors will fix this, and that it may be a vacuum leak??? What do you fellas think?

Thank you sincerily Jason A Neal.

 

How many different threads are you going to post these same problems in?

1. old suspension. You'd have to take it to a frame shop to tell if your frame is bent.

2. Vacuum leak, boost leak, timing issues, etc.

 

z31racer, dont ask the same question 20 times. either start one thread listing all your problems initially, or start an individual thread for each problem (preffered). thank you.
