Hey guys i just bought a new HB. Its a 94 VX. Real nice and clean and the only thing wrong with the car was after driving it for a few minutes. the cars engine would start pulsing.. jumping from 1rpm to 1.5rpm repeatidly.. Any know how on fixing this? If i can fix this the car would be set to go for the mean while. It has the stock vtec-e motor currently.. THANKS!

On another note its a 1994 Honda Civic HB VX.
Just lowered today with Eibachs and Tokico shocks.
Ex/Vx stock lip. Clear corners.
Bone stock with 144k miles clean title.

Picked it up for $2300

Pics soon!

 

Anyone HELP!?!

 

Check to make sure that all of your vacuum lines are hooked up correctly. If one has popped off, that will be the effect (pulsing idle).

Also, try bleeding your coolant. Air in your coolant can cause a pulsing idle as well.

How do I bleed my coolant? Also which vacuum lines are the ones that are easily pop off-able.. Where are they located? Thanks for the help so far.

 

There's a bleeder valve on your engine where the hose goes from the top of your radiator to your motor - that's where the bleeder is. You can open that up or, just open your radiator cap when your motor is cold and run your motor. You'll see bubbles come up after a while.

As for the vacuum hoses - just run your motor and listen for a hissing sound in your engine bay. The lines are usually located on the driver's side, near your intake manifold. Look at your FPR.

Thanks a bunch.. Someone also told me something about a idle control? or IVAC sorry i forgo the exact initials.. it was something like that. Could it also be that as the problem?
