You SHOULD have vacuum on the FPR on a cold start (or any start). Some have hooked the FPR vacuum hose directly to the plenum chamber, and theirs ran okay that way.aidan7777 said:i get vacuum at the FPR on a cold start.
What you DON'T want is vacuum to the EGR valve on a cold start and be sure your EGR transducer is working and plumbed properly. If you suspect you have an EGR issue, just unplug the vacuum hose at the EGR valve, plug the hose, and see if that makes a difference. Dennis
