Today thought it would be high time to do a bit of maintenance. I've had 2 new o2 sensors and a new coolant temp sensor (ECU) sitting in the garage waiting to be fitted as well as 11B plugs.

 

With help from Jimmer we replaced both O2 sensors (which came out quite easily), replaced the plugs with the cooler 11Bs, fitted a new coolant temp sensor and did an oil and filter change.

 

Car idles so much better, throttle response seems to have improved. Turbos now spool up quicker too as I had a boost leak as well! Only a slight one, but was mildly audible.

 

Exhaust is now staying much cleaner. One of my o2 sensors was completely shagged. But replaced both with genuine items.

 

Now that the engine is 101%, it's ripe for a new chip and boost controller.

 

Thanks for your help today Jimmer!

good stuff :D

Forgot to mention, we did the AIV delete too! So got rid of a load of unwanted detritus from the engine bay!

Nice one Si, all ready for the a nice bit of extra power then.

Certainly am! Although I want to double check on conzult to make sure everything is reading correctly before doing that.

Nice one:D How much did all those little bits set you back ? i'm slowly replacing the little bits and pieces like those and all the old rubber piping to silicon to try and get rid of any parts on my 15 year old car before they need replacing and mean time off the road.

Hiya,

 

O2 sensors (OEM) £230+ the pair

Coolant temperature sensor £30

Plugs £60

 

O2 sensors I actually got from Mario who had 2 new OEM ones that he didn't want and I got them for £120 for both, so was very lucky. Just don't trust universal type sensors as they don't always have the same components for the tips and use different metallic substances in their makeup.

Its always nice to get those little niggles sorted out, they really can transform the characteristics of the car, mines all running tip top now, I have a chip and socket but really don't know if I want change the way it is, it has plenty enough power now its running correctly and they're old cars can't decide if the old girl could take a few more horses and still be as reliable as it is.

Great news :D

good to see its running well. you will be amazed when you get the ebc etc.. put in.

Good news mate, Got all of them on this long wish list i have seem to have developed lol

 

glad its running better though :bow:, it's already one of the MOST stunning Z's on the forum and in the UK (imo), so i'm glad you're now thinking of taking the power up a little :D

Nice one Si....... Hope all goes well with the ConZult check :bow:

Cheers.

 

Yeah, it should do. Last time I hooked it up, it showed a lazy o2 sensor and a TPS that needed adjusting. Actually I replaced that too and set it up. So all should be spot on now. :)

Good to hear mate, always nice to fit new parts and see improvements.
