Worth a look. Will try to find the site I got my tubing from Robc1976 (diy freak) found a great place with some top of the line vacuum tubing. Great stuff and can withstand extrenly high temps.

I think the link is in that thread.

I got some extra silicone hose , gonna try swap from main and all the way to canisters.

A mechanic here also mentioned the wastegate could be the cause , stuck or locked in open position or link fell off.

It sounds to me like you are far more knowledgeable about these cars than myself.... But for whatever its worth, I had a bad O2 sensor and my Check Engine light came on. I didn't read the entire thread either, but what I did read, I saw no mention of your CES light being on.

New waterpump and thermostat , fixed broken wires for thermostat and new connector for waterpump.

Cleaned the intake on head.

Tank had 1/4 of 98 octane (europe) and mixed with E85 , ratio around E30.
Filled another 10 liters with 98 octane before startup.

The pump in tank has been upgraded with Walbro 455

When everything was put back together , the car cranked for a few sec , no start , then tried again , no start , then one more , small short starts before dying , read faults in INPA Throttle faults only , deleted fault.

New start and same , short start and then died , read error , cam shaft sensor inlet error 2A9A . Deleted and tried again , then started up and ran little rough so I gave some throttle and ran it at 2000 rpm for few minutes , then let go , eased down to 650ish rmp.

Ran another fault reading , no faults.


Now today after some driving I had one redused power , and now at end of day after filling fuel I had some more faults .

From INPA

Was it your precat oxygen sensors?

[DSrugis]

Did you end up solving this?

if you are having similar issues as OP try resetting all your adaptions. I had some weird throttle codes, car was running funny for a few days. After I reset all my adaptions the car was back to normal.

If the car ran fine before the work, needless to say, it would be related to the work performed. Since it takes fuel and spark to run, look into your injectors first. The vanos solidnoids are pretty straight foward, so look into the injectors, it will throw 02 codes if your ratio is off, and I would pull some oil just to make sure there is no gas in it. If you had a spark issue,you would throw misfire codes. Definely double check everything you touched and make note.
