I have a 96 civic with b16a2. I drive to work and home fine today with no problems. I parked it for about an hour and went out again and started to get a really strong surge at low RPMs. Once I get to like 3-4k RPMs it stops though. Anyone know what it could be?

 

check the tps(for dead spots) check for any vac leaks. is it just the tach or does the car "jerk" ?

 

Vacuum leaks, and either low coolant, or an air bubble in the coolant would cause the problem.

 

Could too much coolant cause it? And yes it is a violent jerk. After parking it for another hour and driving again it stopped. I did fix a coolant leak and when I added more I added a little bit too much

 

no any execs would just flow out when you filled it I think this is a case of air in the system. bleed it and see what happens.

 

Dirty/Clogged IACV would cause this also.
