maybe dash prob! help please
 

So ive had a couple of posts on this...

Wrx is idling high and gone through all the usual stuff...iacv clean/replaced, same with tps, same with maf, n no vac leaks.
Car rins rich too.
I cant seem to sort this n i just spoke to some people. One guy who i got the new iacv off, hes a mechanic n only drives scoobies. He along with others say it purrs right so the rev counter might be off, maybe a bent spring or whatever it is when the loclwood dials got put in.
Another guy also says the rev counter might be wrong but it could be a faulty unit. This guy says that maybe the unit makes my car think its reving higher than what it is causing inaccurate reading and running rich. Could this happen? And if so could it be the speedo converter (car is import). If it has one, i need to look but im 99% sure my speedo is right. Also car only has 110 on clock n only does 110 so prob no delimiter. Again im goin to look at that!

So the main question...can a faulty rev counter cause running rich as well as looking like high idle
And..
Could the unit be replaced with a uk dash or do i need an import dash with a speed converter on it?

Anyone know anything at all on this. Any bit of advice is greatly appreciated

Surely it's not beyond a decent mechanic to do an ACCURATE measurement of the rpm?

Can I respectfully suggest that getting the car to a respected specialist is your best bet?

Yeh thats true but he doesnt have his garage anymore or alot of his gear. He is gettin on a little now n just does stuff from home to get by else he would of done it for me.

Also normally i would go to a specialist or even just a garage with this problem but money is tight lately due to unforseable circumstances. I cant really afford my car anymore n i am desperate to get this car sorted As cheap as pos for the mot. I really dont want to sell after because i love scoobies but i might have to. Hopefully not! Maybe if i get the richness sorted then fuel costs might not be sucb a problem

I take that back actually! I can afford it, i just need to get an mot n keep on the road, im just unlucky about my finances messing up at the wrong time. Sods law!!

Wherabouts in Lincs? Could you get it over to Carnetix in Melton Mowbray?

Sure can. Im only in grantham. In a scoob that will b 10 mins away at the most lol. What is it you could do for me n how much mate?

I'm not Carnetix. Give 'em a ring and ask for advice, book it in and have it looked at by professionals who understand these cars. They will give you a price for a look over the phone, and discuss what needs done when they've seen it.

Top people.
