Hi all, I've not posted on here since joining the forum, despite there being a newbies section, but felt the need to let you all know what I'm doing to the '91 UK Z32 TT I bought at the weekend.

 

To be honest, she's a bit of a shed, but I'm determined to get her looking and performing well.

 

She's got an idle problem which sounds a bit like a misfire...possibly due a fuel leak (I can smell fuel). In addition to running the diagnostics and checking for leaks, I'm getting my mate Matt (who will probably be using this forum ID to ask for help) to service my car and give her a good going over. He occassionally helps out at an MX5 specialist, so knows all about those, but will have a steep learning curve with the Z! Here's what he'll be doing on Thursday:

 

Engine flush, oil and filter

Spark Plugs

Gearbox Oil

Diff Oil

Coolant flush

Underseal

Investigate the wiper washer wiring (they only spray when the rear wiper switch is on???)

Change brake fluid

Check PAS fluid

Check tyres

Compression test

Renew air filter

Find out why you need to hit the N/S headlight to make the lamp come on

Replace wiper blades

Adjust handbrake

Clean Throttle Bodies

Clean the Idle Speed Control Valve...god knows where that is!

Grease door/bonnet/boot hinges and latches etc

Clear Targa drains

 

Other jobs to do in due course are:

 

Remove the foam spoiler

Change the discs and pads

Re-upholster the seats, door cards, centre console etc

Change gear stick bush

Replace Electric Aerial

 

I'll update as and when each one is sorted, or if we need any help! Photos to follow!

great stuff mate - welcome to the club! its good to see lucky Zs with owners who clearly show enthusiasm. keep us all posted on how its going :bow:

sounds good, if got a misfire try and clean all the injector and coil connectors. Good luck with the project. You got any pictures?

another zed rescued...

 

Good work mate and you can count on the guys helping out on this forum

I'll get Matt to take a look at those too...cheers.

 

No pictures yet...but I'll post them up over the next few days.

 

Both of us are enthusiasts, both coming from MX5s, he's now got a slightly modified S2000 that makes mincemeat of me in the corners, and 'just' manages to squeeze ahead on the straights. I think I need to get to grips with the car a bit more! I'm sooo much more comfortable though :D

welcome along mate.

 

With a bit of money and time spent she'll soon be good as gold... glad you are enjoying Z life :dance:

Welcome mate. been sorting similar jobs on my new Z lately. It's a good feeling when it all comes together :D

Thanks for all the friendly welcome messages :)

 

Me and my mate Matt made some progress this evening, finding codes 13 and 34 stored in the ECU.

 

Both the det sensor and coolant sensor connectors are cracked in some way, and the coolant sensor has a build of verdigris on the pins, so we'll clean those off before delving any deeper. After reconnecting both of those, the engine idled perfectly! I don't expect it to last, but it's a start!

 

Out of interest, is the det sensor resistor mod, a permanent fix? Or should I replace it when it's accessible, or ASAP?

 

Also, out of the two codes, which would you expect to cause the idle problem?

 

As for the N/S headlight that only came on when you hit the headlight assembly, Matt found the relay, removed it, reconnected and all is fine...how bizarre!

Hi all, Matt here, I've been working on Tom's Z32 today, and made the following progress:

 

Renewed Diff, Gearbox and Engine Oil

Replaced spark plugs (one coil pack snapped in half!)

Undersealed

Coolant flushed

Located an oil leak (N/S cam cover gasket by the looks of it)

Checked tyres (fine)

Inspected brakes (fine, but need new disks within 6 months)

Replaced air filters (will fit induction in due course)

Renewed brake fluid (it looked like Brandy!)

Checked the PAS fluid

 

All of that in four hours, and having never worked on a Z before, I don't think that's too bad!

 

The downside is the car ran on safety boost this morning, probably due to code 34 (det sensor), which we obtained last night. I've also ordered a new coolant temp sensor, so will hopefully get rid of the code 13 as cleaning the connectors didn't work 100%

Well done, that looks OK, nice plate too. The resistor det sensor mod tends to be permanent as a replacemnt det sensor is quite an involved job, i.e. plenum off, unless you reposition it. It is usually the harness that fails and not the sensor which is a bit more easier to replace. Loads of help on here, keep plugging.

Thanks 'old zed'. Matt hasn't got round to checking the harness yet, should be some time next week. If the sensor itself has gone though, he'll be relocating it for me as per the forum sticky :)

She's still running on safety boost, even though the ECU shows code 55. Having read alot about det sensors on the forum, I'm convinced the det sensor/wiring is the culprit so I'll get it looked at this week. N/S manifold is definitely blowing too...that must be a bitch to replace...does the engine need to come out for this?

All will get answered when they all return from JAE bud!!
