NB RUnning Poorly...any ideas?

[Steampunk]

Thank you master Yoda. This young Padawan thanks you, and from now on I will be mindful of the future, but not at the expense of the present.

I'm not Yoda, I'm Two-Hump Kenobi!

You really want a blue car!

[Steampunk]

I reeeally want a bluuue carrr ....

Does it include changing hands at a hundred.....

ONLY Joking Craig.....

Craig, stop moving your hand in a back and forth motion !

Right...the early NB8B's that had the shuddering clutches replaced are prone to this error as the neutral switches wiring is clipped to the under chassis of the car, and when the clutches are replaced the dealers just cut the ties and never bother to replace them, which in time leads to the wire breaking internally from vibration and fatigue.

Now...what happens is the car thinks you just sitting there stationary and revving the crap out of your car, and not actually in gear, hence it never actually uses the readings from the O2 sensor and it drives like sh*t until it warms up and goes into a default setting.

P.S. I'll type up a novel next time perhaps or maybe you can just trust me!

Thankyou. I shall try that...dont suppose the sequel to your novel would describe how to replace it?

[hamish71]

I can also say, its not the spark plug leads (changed), and I dont think its the coils. (Had them checked today....but to be honest, all the guy could tell me was, they are both the same! He was from scrorcher distributors here in Melbourne, recommended above. His test equipment said they are both under voltage, but he made it clear that his equipment was not the right thing to be using. All he could say was, they are both exactly the same!)

Hmmm, sounds exactly like the problem I've been having for the last 6 months. Mine runs rich on startup, exhibits the same symptoms and clears up with a bit of temperature in it. Same stall problem on idle too. I've tried another ECU and coolant temp sensor, with no change.

Any chance this gearbox neutral switch doover is used on the NA6?

I'm told its a shitter of a job as it's on top of the gearbox.

[hamish71]

RIght, I have changed a shitload of things, and ven verified that the timing had jumped a tooth, and was thus out...but still...not quite right....

[JBT]

How could the belt jump a tooth? Not possible if the tensioner is set right. Unfortunately, it sounds like a poor belt replacement job.

So you've fixed that and it still isn't right? Checked the timing to see if the crankshaft pulley has moved?

[hamish71]

crankshaft pulley and key are in perfect working order....

What are the chances the cat is screwed, thus restricting exit of exhaust gases????

[JBT]

What are the chances the cat is screwed?

Very little at 150,000km. I've seen MX-5s with 200,000+km on the original exhaust and all OK.
