Yeah have the boost gauge. Seems to be jittering when idle, boosts sometimes holds at 10psi then will hold at 15psi then other times shoots to 20psi. So from my research that means n75/vac lines/PCV.

Going to service the recirc valve replace the lines.

Was going to just put in a catch can for the pcv.

From what I can see these mods were done car was mapped for them

P0171 code on the basic obd scanner.

Just had it in the garage for the manifold gasket thought that was the issue but no better performance just less tractor like now

All the PCV hoses under the inlet manifold are the usual places for a leak. I'd start there.

If you take the battery and battery box out, it makes access way easier. Get a flashlight and inspect the pipes for leaks of loose hoses.

Yeah all hoses up too seem to be in tact. The hose off the rocker cover is a lil soft so replacing that.
So il have to check under this evening.

Also wondering...the car boosts a lil smoother with n75 unplugged... wondering if that would make any difference to have it unplugged for the emissions test?

Shouldn't have thought so. Pretty sure with it unplugged the lambda sensors are disabled and it's in open loop, but never tried it

New full set of boots. Road trip next week so replaced my ageing tyres that had really bad cracks around the edges.
The guy in front of me ordered two tyres £742 he got quoted.
I’d love to know what they’re going on cause I’m never having one whatever it is. :sleepy:

Do you have a boost gauge? you could probably tell if you have a boost/vac leak there first

People do weird stuff to the PCV system, you really cant go wrong with the standard setup. you might try getting a cheap PCV pipe kit for that.

lean can be a few things, you could even have poor fuel pressure. What codes do you have?
Apologies actually re read my message. Not got the lean code have the rich code.

Emissions are .59% co2 at 3000rpm. Need to get em down to .3. don't think that it's the cat but having it checked hopefully next week
