when I start gradually excellerating between the ranges of 2000 and 4000 rpm the car will freeze at let say 3200 rpm if i let of the gas it stops but if i just keep steady where i am it will feel like someone is pushing against me and then the car will release and climb rpms normally again, has this happened to anyone? its very hard to explain I tried the best i could, just thought id check to see if its happened to anyone else before i bring it in.

 

What engine do you have?

 

He's got a '99 Civic Si.

 

Well now that we've established that.........WHAT ENGINE DO YOU HAVE? So you have a stock engine, no swaps?

 

Just didn't know if you didn't catch that...I just assumed he has the stock engine.

 

well a stock engine on a 99 Si is a b16a2

 

Wow, 4 replies that have absolutely nothing to do with his question. Congratulations guys

To the thread starter...I'd say there might be some gunk in your throttle body that is causing your throttle to stick. Try unbolting your throttle body and cleaning it with carb cleaner and see if that does anything.

 

haha yes i have the stock engine the b16a2...thanks for your help BauleyCivic i will try that
