I was just guessing at the HT weight. At 38K I've never had my valves adjusted, didn't think at this point the car would need that done.

 

The valves would have to be really really really out of adustment to cause performance issues. Generally they just give you a ticking or tapping noise as the only symptom.

So, did resetting the ECU help?

 

Maybe the hardtop makes your car quieter thereby giving you "feeling" you are going slower.

 

I'm going to reset the ECU today, I'll come back with the results tomorrow.

 

With the ignition off, remove the #25 BACK-UP fuse (7.5A) from the under-dash fusebox. Do not reinstall for at least 10 seconds.

 

Did you DRIVE your friends cars or just RIDE in them?? Sometime the passenger seat can feel faster. I would definately atleast reset the ECU though since its such a simple matter. G/L!

 

Dont forget to tighten the throttle cable. If it has too much granny slack, it will feel sluggish...mine did until some local members showed me how to tighten it on a detail day. I believe you lossen a nut on the thrttle cable wich alows you to move it back tighter. Chek to see if there is a good amount of tension or if it is easy to push in with your finger first. There has to be a post on here somewhere...

 

Hey Guys,

Reset my ECU yesterday and it made a pretty big difference. Can definitely feel the car pull harder in the 3500 to 5000 rpm range, and Vtec kicks in harder as well. I guess the computer was either stuck in granny mode or was perhaps used to getting low octane fuel. Thanks for everyone's suggestions and tips!

Glad everthing worked out for the best
