finally got the vac hose job finished and the car drives a lot better and has sorted the boost problems i was having and am now getting a nice 10-8-10 boost reading but have now got a high idle of about 1100 rpm also when left idleing for a few mins the revs start hunting ,god will i ever get this car sorted ive only driven the dam thing 3 times
If you had leaks before and now you\'ve fixed \'em, all your idle control stuff will need readjusting cos it\'s got used to managing the leaks!
cheers for the reply ,is there a walkthrough for setting up the idle as i also cleaned and polished all the throttle linkage so i suppose this will affect it also
Idle speed adjustment:
bring engine up to normal operating temperature
connect TEN and GND on diagnostic connector (paper clip works well)
make sure the wax rod operated lever completely separates from the fast idle cam
adjust idle speed to approx. 725 rpm by turning the idle speed adjusting screw located UNDER the throttle body between the two 10mm cap nuts that attach the charge air pipe to the throttle body
if the idle speed is too high with the adjusting screw fully screwed in (clockwise), unlock and turn (counterclockwise) the primary throttle stop screw to give you more adjusting range for the screw under the throttle body.
while adjusting idle make sure the fans are not running
remove the TEN-GND jumper and verify that the ISC system takes the rpm up to approx. 850
How did you get the intake elbow so clean & shiny?
Cheers

im thinking of attacking the rats mess, what diamiter of silicone hose do you need to use? do you need any new hose clips? how long does it take to do
thanks
Gavin
thanks guys will do the idle adjustment tommorow
jon : i painted the intake pipe with an alluminium affect paint as it was well manky
gavin : i used 4mm silicone hose i didnt use any clips either and they seem to be holding fine but its early days yet :)
and the job took me a day to finish but my ppes were all wrong to start with so i ripped them all out and did them one by one from the vac hose diagram
I have just bought these silicone pipes from Ebay I think its a
good price. 17.99 including postage
10 FEET OF 4MM
4 FEET OF 6MM
2 FEET OF 10MM
marshall2702 can you advise please, I thought other diamiters of pipes were needed, I am going to try and do any pipes that can be replaced.
I am however going to use cable ties on my hoses just in case. You can get colour coded ties from B+Q will cable ties be Okay, does anyone know?
I am going to tackle mine shortly:(
Gavin the guy still has some left.

id imagine the cable ties would be ok and yes there are other size pipesbut on mine these had allready been changed when the engine was rebuilt so i didnt change em
i may get a set of these good selection of sizes, im still waiting on my other hoses to come its been 5 weeks now, got them from PCAmotorsport was told i would get them in two weeks :reallymad going to give him till friday then i want my money back,
Thanks for the info marshall2702, glad I bought a selection now, I am sure I will be needing something else when I come to do it.
Mine took that long form him as well Gavin, but they were good quality when they came.
Cheers
just ordered a set of the ones you got might as well do all of them, guess everyone in the group buy is still waiting uk customs have a lot to answer for, blitz didnt have any probs in holland, just goes to show he got his yesterday all were posted at the same time,
just out of interest when i do the rats nest do i need any new gaskets for the plenum?
According to Mazda you do need new gaskets.
However..
The Upper to Lower intake manifold gasket can take about 6 removals before it needs replacing according to WGT. You can remove the throttle body with the UIM so no need to split that gasket. The \'O\' ring from the throttle body to the intake elbow can take loads of removals, i have split this section 30+ times with no leakage.
hope that helps.
