Living with a Porsche 944

As I fitted an S2 intake onto an S engine using an S fuel rail - the fuel damper has never fitted nicely to the intake as it should. It wasn't an issue per se but I wanted a neater factory install. The solution was to drill out the one mounting plate hole so the damper could be attached using the throttle body linkage attachment bolt. Not a very complicated procedure but a much tidier and more secure solution.

In order to maximise the airflow through the intake I've been meaning to replace the intake j-boot that fits between the throttle body and air flow meter - it's had a nasty crimp in it since I installed it and it really wasn't the best solution. A 45º elbow 80mm to 70mm reducing silicon intake hose was purchased from Demon Tweeks as well as a 19mm O.D. Revotec self-sealing take hose off from eBay. The silicon hose comes with enough length on either end to trim it to fit. I then fitted the hose and mocked it up in the engine bay so I could figure out where to fit the take off for the hose that runs to the ICV. After I was happy with that fit and had marked the point at where the hose should connect, I removed the j-boot and got ready to make the hole for the take off fitting. The kit comes with a neat punch that makes the hole for the take off. A quick smack of the rubber mallet and voila! Then insert the barb connector and tighten up the lock ...

I've been hunting down an intermittent idle issue on TheHoff since our last Brand Hatch excursion - which led not only to testing & replacing parts but also eliminating others and making one completely from scratch! As the Idle Control Valve (ICV or ISV) was the suspected culprit the whole intake manifold, throttle body, AFM and filter had to come out - oh and the fuel rail too. Actually it's less of a phaff than it sounds. As ICV's are around £150 to replace I wanted to test mine to be sure it was faulty. After removing it from the underside of the intake manifold I jumpered it directly to the battery and it works perfectly with a very solid "clunk" when activated and deactivated. So that wasn't the issue. I also made sure that the hoses running from the ICV to the intake and the J-Boot were correct also as I suspected I may have routed them incorrectly - turns out that was also correct according to how I had fitted the ICV. So wha...
