I just did a swap for a buddy and this is all kinda new to me....

We got the motor together and running last night. The car runs good and pulls good.

My only question is a idle the car starts to "lope" or "cam". I know that this is usually caused by a vacuum leak but it looks like they are all up to par. The head is a gsr head with gsr cams. Do gsr cams produce this or is this something else.

Thanks alot

 

What's it idling at?

 

Make sure your timing is correct make sure your t-belt hasnt jumped a tooth.

 

Is it idling rough, or is the idle surging up and down?

 

idle air control valve perhaps.

 

Its idle surging, thanks for the correct word. The IAC is fine, I just rechecked the timing and its still TDC. Its idle is at about 900rpms.

 

What kind of flywheel? Have you calibrated the throttle position sensor yet?

 

yeah we calibrated everything. I adjusted the idle a little and seems to not do it as much.
