Ok

After ECU diags, changing my PTU to a new series 2 one, changing the temp sensor and the harness, doing a oil and filter change, cleaning the air filter and resetting the ECU I still couldn't solve the hesitation problem.

 

So, I took the car up to Andy P this morning and he plugged in a conzult and ran a few checks, it was a case of... "good, that's perfect, yep, ok then.... WTF, that can't right" LOL

 

Seems my left O2 sensor was running at 2.4 v on idle rather than the standard 0.25 - 0.4. When Andy disconnected it, it defaulted to 0.33 so Andy adjusted the TPS and idle. I'm now running at 750rpm idle (rather than 1,100 rpm). So I'm going to have to order a left side O2 sensor from "Neeesan Texas". Andy also changed the MAS over, as my one looked a little suspect - the mesh had been taken off each end :confused: (may not be anything to do with this but I'm giving it back next week anyway, so we will see).

 

Even with the left side 02 connector disconnected and running at a constant .33 the car feels absolutely rapid compared to what it was. It's much smoother with no hesitation at all.

 

I hope you enjoy the crate of Guinness I bought up Andy. I really appeciate your help today :). Just wanted to let everyone know.

Thanks

Nice one Stu,top bloke is LittleP;)

Yeah I'll probably get a few more bits form them also.

 

I bought one of their drinks holders last time LOL. IT's very well made though (fits in the ashtray slot). I though it may get in the way of the gear stick but it's fine (I don't keep it in there all the time, just when I need to drink and drive - soft drinks only obviously)

 

Was gonna order some mats but Andy told me his cost over £200 after tax and other charges.

 

Hmmm just looked at the link and they use the old Driver and passenger side chesnut.

 

the one I need is the left hand side (i.e. passenger) but is ther passenger equal to our driver side ?.

dopes anyone know.

 

I'll probably get both anyway.

You're not out of the woods yet, all I did was find a problem you didn't know you had !!! ;) You now have to replace the O2 sensor (which can be fun) and we still have to get the TPS set correctly and the tickover dead on - at the moment I don't think you're actually getting full throttle !

 

As for O2 sensors, you would obviously need the driver side (from a US car)

 

There are probably a few other parts that you could get at the same time like PCV's and hoses.

A handfull of the dashboard trim bits (http://www.courtesyparts.com/Merchant2/merchant.mv?Screen=CTGY&Store_Code=CP&Category_Code=Int_trim) because people are always asking for these, they cost naff all and weigh naff all.

A bucketfull of oil drain plug washers, because they're bound to be cheaper than here.

 

Incidentally, I bought my floor mats from http://www.japaneseaccessories.com/, but their web site seems to be AWOL right now.

 

PS I do like people who leave crates of Guinness behind ! :D

:eek: So you mean I can actually go faster than I am at the moment. :cool: .

 

I'm still thinking about this afternoon when you said "ahh 15%, you must drive quite calmly". ;) ;). ROFL !!!!
