You mean that RPM's go up-n-down in 1 or 2 sec. intervals?

Idle is probably set too high.

What was wrong with your EFI?
For the idle thing, you're probably low on coolant. The coolant temp sensor will pickup air bubbles and oscillate between cold and warm idle speeds. Check that first.

The EFI the wire splices where makeing good conction but teh wire was cracked and shorting out that is why it would run then die. repaced the whole wire and it works. the pulsating stoped when i unpluged the EGR so now i dont know if i need it or not.
