Calling the DJet Ninjas. I picked up this intake manifold a couple of months ago and had some questions first how do you tell the difference between a 1.7 and a 1.8 liter manifold. The second question is on the throttle shaft there is a bit of play, enough that I'm sure this would cause an air/vacuum leak. Should I be concerned about it or is this a non issue. Thanks for your time.

I just went through this a few weeks ago. There was play in the throttle shaft so it would move laterally ever so slightly (but noticeably) in the body. The net effect is that sometimes the plate wouldn't close properly and the TPS would not "engage" the idle circuit. I'd get inconsistent idle mixtures. It was a minor issue, but sometimes those can drive you crazy. When it wasn't minor is when it got worse and the plate started sticking way open - usually when I started the car in the morning to go to work (I'm sure my neighbors appreciated it jumping to 3000 rpm immediately at 6:30 am).
I refurbed mine following the basics in this thread: http://www.914world.com/bbs2/index.php?showtopic=206017 |
