Not as much boost after cambelt change?

[chrisjunkie]

Hi all,

After having my cambelt done at Winger Subaru Greenlane last Wednesday, the car seems to not boost as much and is a little laggy?

They did an engine diagnostic to try and get rid of the stupid engine check light because of my knock sensor. It is since then that the car just doesn't seem to play as nice :-[

What do you recommend I do? I will definitely be ringing Winger tomorrow but are there any ideas to what it may be?

[driftrex]

i would take it back to winger, if its since they had the car then they should be fixing it.

id say its to do with your knock sensor...

[Johnnynz]

Has it actualy seen a drop in boost (have you checked on gauge if you have one?) or does it just feel less responsive.

[chrisjunkie]

I dont have a boost gauge but it just feels less responsive - doesn't put you "in your seat" the same as it used to.

[chrisjunkie]

Took it in again and they have identified it as the knock sensor... $400 to replace :-[

had to be done i suppose

[Guest]

what! $400 thats dear.

[chrisjunkie]

yeah thats installed!!!

I was going to get other quotes but never mind they did the diagnostic so might as well have it done there

[hhhh1]

ive got one here you could have had for $50..too late now

Sensor for my old GT cost me $120 and installed it in 20 mins in the dark on the side of the road. Pays to ask how hard stuff is before you pay someone else to do it.

Twin turbo is a bit harder to install Ben....

[chrisjunkie]

Yeah and if anything goes wrong I can go to them and ask questions.

Two hours labour and the sensor at $160. It's done now so never mind

If they reset the ECU then it will most likely drive different, as it will have reset the fuel and ignition maps back to factory.

Does it then learn new maps and what not?

[Guest boostin]

Yup. Just takes time.

[chrisjunkie]

Oh ok thank goodness for that!!! It did still feel a bit sluggish lol but as long as it gets better I am happy.

Such a nice car to drive and is actually quite economical if I dont want to boost all the time.

;D ;D ;D ;D
