Yeh with purpose built throttle bodies costing £800+ this is hopefully going to produce the same or similar result for a considerably cheaper cost, well thats the idea.
With work on the delta turbo, other cars and a shed to build, the HPE has just sat on the drive waiting to have work done over the last couple of weeks. Items that needed attention was get to the bottom of this poor running at cruising speeds, and the "R" word!!!!
I started off taking all the induction hoses off, as I thought it might be related to the vacuum pipe from manifold to fuel regulator being blocked or partially, funnily enough when I checked the pipe was clear but on the manifold and regulator the ends were partially clogged with dirt somehow...
Put everything back together, started it up and no difference I could hear at idle, still running a little rough. It wasn't until I looked again and no.3 looked like this...
Turned it off, got the spark plug socket on it and it was loose! I havn't really touched them since doing the head a good 2 years ago now so may have been slightly looser than the rest when put in and with various track days and the rolling road might have worked itself loose.
Not only this, this is a normal plug...
Check the top of the same loose spark plug out...
I can only describe it as a tiny bit of stone that somehow made its way onto the top of the plug. Obviously while I was at it, I checked all the HT connections and found that 3 of the 4 tops of the spark plugs were lose, so they were done up hand tight and then with pliers, hopefully this has solved the problem but as I decided to get the welder out i've not had a chance to test drive it.
With MOT time coming up very soon, its about time I sorted out the hole thats been in my floor too long, its also the hole which was produced by a MOT station I don't normally use last year, and didn't even put an advisory down about it
After poking it around this was the beauty...
Wire wheel and grinder came out...
