need4speed Posted February 23, 2017 Share Posted February 23, 2017 This might be old news but thought it might save people some aggravation. Regarding the "heat delete" mod where people get rid of the heater hoses on the Hotwire plenum. Everything I have read on this suggests that 2 of the bolt holes for the heater plate are open to the interior of the plenum causing no end of tickover problems/throttle hesitation etc if not blocked. Well scratch that. There are actually 3 of the bolt holes open to the plenum. So if you have blocked the inner 2 holes that are obviously open and are still experiencing problems, this could be the reason. Just thought I'd share as I've just discovered this by complete chance.

Bowie69 Posted February 23, 2017 Share Posted February 23, 2017 I think I just left the plate in place,... with the pipes knocked off Quote Link to comment Share on other sites More sharing options...
need4speed Posted February 23, 2017 Author Share Posted February 23, 2017 Yep that's what I'm going to do Pete. I know however there are a few that removed the plate and decided to blank the bolt holes. I was just a bit surprised to find 3 open holes when all I can remember hearing was that there were 2 open.

bodumatau Posted February 24, 2017 Share Posted February 24, 2017 @Bowie69, did you leave the pipes to the throttle warmer open? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted February 24, 2017 Share Posted February 24, 2017 Yep, just knocked off , so I don't slice my hands when getting injector plugs on. Quote Link to comment Share on other sites More sharing options...
