When I rev to like 5000 in first to third the motor seems to bog and then pick up after that?? I have a b18c and running a pr4, any one have anyideas, I put high octane gas in and fuel injector cleaner. Still does it though, I'm stumpped??

 

change your plug wires and cap and rotor.

 

seconmdary runners never opening. if you run the car on a pr3 ecu it wont the open the runners, they way to fix this is a skunk 2 manifold.

 

1.the pr4 is a LS b18 ecu
2. the ecu has no VTEC
3. your GSR secondaries arent opening
4. the pr4 fuel maps are *** for the gsr motor..

GET A GSR ECU.!!!

 

Isn't that normal for a car to do that? If you were at 5000 in 1st and shifted to second it would be probably a little over 2000 or something, and since Hondas have no torque it is going to go quite slow at that. So the solution is to not skip 2nd gear!
