Hey I'm new here, I have a some questions that I'm sure you can help me with.

Ok, I have a 2002 Model Evolution VII (4G63), I don't use it much but i love it. Modded with bolt-ons only like down pipe with JUN exhaust and filter replacement and suction kit, intercooler piping kit, Sequential Blow-off Valve, lightweight (racing) Flywheel, and etc..

For the past couple of weeks, I noticed something different, if I speed up and go into high RPMs the car cuts off alone (like going into safe mode or something), like its overboosting and telling me to slow down. I have no idea y! I'm guessing that one of the pipes are loose?

Another issue is that once I had my clutches changed, and when they changed the clutch, the steering wheel feels different, so now when i turn, the steering wheen goes from soft to hard to soft again ....

Please help me if you have any idea whats wrong with my evo and how to fix..


Thanks!

 

How many miles and was timing belt every changed.

And check tension on you serpentine belt. My tensioner was worn and gave me a loose belt, thus giving me weird noises when i made sharp turns.
Also check your steering fluid

 

My car has 80K miles, and I'm not really sure if I've ever changed the timing belt. The steering fluid is not the issue, I think something is wrong with the steering wheel set up from the core.. Something like that.

 

Sort of like a fuel cut.. Any idea what might be the problem?

 

Is there any play in the steering at standstill? Also have the you checked the power steering belt tension?

 

I been through this before. When I boosting hard past 6000rpm ~ 6500rpm it feels like fuel cut at high rpm, thats mean you got bad plugs. Try to change the spark plugs to a better and colder rating ones. Hope this help.
