SV: [Gmecm] 1227747 Questions

[dgilbert78 at juno.com]

Hello: Make absolutely sure that the vacuum ported to the MAP is not
restricted in any way. lots of times there is a vacuum leak in the MAP
hose or the port in the TBI is carboned up. Put a vacuum gauge on it and
looks just fine, but vacuum is delayed, and MAP is slow responding, hence
forth engine will be fuel starved and die when throttle is cracked.
good luck
