Car is back.
Here's pics of the intake manifold :
When I got the car back, my mechanics told me that the car got a high idle and not stable.
Idle was minimum at 1200rpm, and going up to 1800rpm! Like someone was playing with the throttle! A bit bad while driving.
When I got home, I got my laptop and plug VAGCOM to check. I do a throttle body reset! Get the fault code away and it work fine. My mechanics told me the when the EGR was plugged, it was acting funny, so it was disconnect!
I drove like this and I was at 760rpm at idle!
I got back home today, plug vagcom, eease the fault code, plug the EGR again, start and test drive, no faults codes! Cool!
The good things is, I use to have fault codes from the lambda (O² sensor), now, I got nothing back from the sensor! Looks like it's fine! I drove 100km (62.5 miles) so far, and nothing came back, usually, it come back within 30 km (18.75 miles) I cross my fingers for this!
So far, engine is smooth, and in mid and high rev, it feels more powerfull. On 4th gear getting in high rev, engine feels pushy! shifting in 5th, looks like I got
problem getting really high.
I need a remap, but it's on the way. Without it, it runs okay, might run better after!
I'll keep you updated on this!
