Winter Porting Project Done!
I was having problems last summer with my idle and intermittent SES light - which I ultimately figured was a problem with the throttle body binding - so decided that since I'd have it all apart over the winter to repair the TB - might as well port the top end at the same time (and take out the starter and clean the valley)
I sent the TB off to Marc Haibeck to repair and Port. I arranged for Lee Gaffigan to exchange my Airhorn, Plenum, Intakes and Coolant Tubes - which he ported and Powder coated for me. I got new gaskets and bolts from Jerry. Finally got her all back together this weekend. I could never get the car to idle below about 750 without turning on the A/C, and I had IAC of zero when the car was warm. The Engine now idles smooth as silk at 675 RPM and with the engine at operating temp I have an IAC of 23 (Marc promised I'd get 20) Marc, Lee and Jerry are all very helpful and great to deal with - wanted to thank them for their help / service - couldn't have done it without them. I'll post before and after dyno results once I have the new results. Here's a few photo's....
