TOP END REFINISHING
2nd ed.:
DEFINITELY read Cliff's - user <Dynomite> - links when he links them. They're not always directly to the pertinent information about what you're on at some point in repair - you'll have to read it ALL to get to the info, but it's ALL there, and you HAVE to go through it. (Thanks a ton for that stuff Cliff). Use your bookmarks tool in your browser for the info when you hit it, and note that sometimes you'll run across info that's IMPORTANT at a LATER point... edit: This is continued from the DataMaster thread, for 'hesitation' diagnosis http://www.zr1.net/forum/showthread.php?t=21259 ------------------------------------------------------------------------- Next in the 'Hesitation' troubleshoot is spark plugs and wires check. Meaning access to the distributor to yank the wires. This is about to become a Plenum Pull. ed.: This is now a plenum pull thread. Link to the best procedure / tips / tricks?

Re: Throttle hesitation diagnostics?
I guess if you are going under there it might be wise to check all vac lines, check valves and mechanical/electrical connections too.

There is no distributor. You mean the DIS and ignition coil housing. The biggest PITA for me are the 2 Ignition Module connectors up under the plenum. Other than that it's about a 15-20 min job IF you don't need to drain the coolant. That TB looks like it hasn't been off for some time. Any obvious signs of torn gasket or vacuum leaks.

Re: Throttle hesitation diagnostics?
That the cam sensor plug. Feel underneath, should be a tang to unlock it. Be careful tho not to break the tang. Pull down and push back plug at the same time. You also unbolted the DIS connector right?
