I have a 1993 Acura Integra da with b18a and it is fluttering at about four to five thousand rpm... It happened on my way home last night after the car was warmed up. I did notice this morning it didn't do it when the car was cold but after it warmed up it started again.it's not horrible but I'd like to fix it. It still runs okay, not the best, no misfire.

I was thinking the tps, igniter in the dizzy, or maybe even a throttle cable but I don't wanna throw money at it and my power probe is inop. If anyone has gone threw those issue please help!

Bare with me I'm a new user.


I do have an exhaust leak after the cat...if that could be something...

Just did six puck clutch as well could the clutch be slipping at high rpm? As if it were misadjusted?

 

Fast idle thermal valve. open it up and screw it back in.

Edit: re read problem. this isn't it.

 

Because it happens once engine is warmed up and not when cold, check the ECT sensor. 94
