Dear distinguished forum members,
This is my first post, and i believe it will not be the last.
I thank you in advance for your help in bringing back, this wonderful car, to what it should be.
I've purchased the car recently, and it was missing care as owned by a person who neglected her during 10 years.
I did already a basic maintenance : replacement of engine, gearbox and rear axle oil + filters + spark plugs (coils are recent).
My issue is that I have the feeling to drive with the choke inserted ( RPM are stable at idle : around 900 rpm): When I release the throttle pedal and press the clutch to change gear (up or down), the rev keep increasing by 200 to 500 rpm.
On flat road, if I release the throttle pedal, the car keeps its speed (cruise control is off ;-) ).
In addition, it miss power aswell compaired to my Volvo C70 (1.75 T and 150 hp)
Despite having no error codes on my OBDII reader, neither messages on the dash, I was suspecting an air leak. So I did the following :
- uper and lower intake gaskets replacement,
- injection nozzles cleaning (ultrasound) + o'rings replacement,
- 2x VVT solenoid check, cleaning + cam cover gasket replacement
- 2x Cam cover gaskets
- IMT check + gasket replacement
- check positive cranck-case breather pipe & elbows : I've replaced the pipe as it was a little bit cracked
- 2 o'rings of the full load ventilation
- Mass air flow sensor + air temp sensor cleaning and control
- head temp sensor control
- Break assistance vacuum hose and connection control
Everything looks good, but I steel have the revs increasing every time I'm switching gears.
Any Idea?
Thanking you all for your support
Marc

@DeepSound80, how many kilometres does she show on the instrument cluster?

Does she have a manual or automatic gearbox?

 

Hello,
She's having manual gearbox with almost 130 000 km

 

To test for a leak use the fuel trims. 900 sounds high.
