Gtr Problems And Advice

[Cooper]

I posted a thread the other day about my exhaust temperature sensor (http://www.skylinesaustralia.com/forums/index.php?showtopic=103482)

Since i re-screwed in the sensor it ran fine for a day but now the warning light is flashing again, its not the engine light the symbol looks like a cat converter with steam coming of it, i assume its a temperature warning light. Since this light is still coming on and off while im driving does that mean that i have to replace the sensor cause its damaged? (since it got filed dragging on the road) if so how hard is it to replace (can i do it myself) and is it an expensive item to buy? Is damage going to be done to the car if i keep driving it with the warning?

The second problem is from what ive read is common but i just need clarification. When im driving my car a bit harder (above 5500rpm) it stuters a bit under boost and the revs are not smooth to the redline. From what i can remember it is most likly the spark plug and or the coil packs that have given up and can no longer provide a good enough spark under high boost pressures. Is this correct and if so what sort of price am i looking at to get new plugs and or coil packs (splitfires etc) and how easy are they to install can they be done by most people? or are they more a job for an experianced auto electrician?

Any help regarding these question will be appreciated, thanks in advance.

^^^ Thanks for that its what i assumed it was but is it going to be a problem driving around with it acting up?

it means your cat is getting very hot, and that be caused by a number of things, e.g blocked cat, engine running lean etc

or it could be a stuffed sensor

Are the sensors an easy thing to fix? are they a plug in plug out sort of thing?

[Cooper]

Just did a bit of searching and found out that the exhaust sensor is not needed and wont cause a problem so i will remove it all together and plug the whole.

I would still like conformation on the second question regarding inconsitant revs, is it the coil pack and or spark plugs?

$25 for a set of plugs will answer that question

Cool thanks for that, ill go and get some NGK spark plugs on the weekends.

I had that Exhaust Temp Sensor light on in my GTR for a while, not long after I had new turbos fitted, the car started running like a dog and the Cat was steaming! (Cat and dog reference pure coincidence! )

So initially I thought the Cat internals had melted...and well...had it removed.

Car still ran like a dog and would only run on the smallest of throttle openings.

To cut a long story short, I stumbled across the problem when removing the Plastic cover which bridges the rocker covers on the RB26, Not long after having new turbos fitted I painted the rocker covers, and had removed this panel, when putting it back on I did not plug the ignitor back in properly (Mounted on the panel) hence the plug came loose and car ran like shit.

Put the plug back in and No problems to this day!........

As mentioned, plugs around $25, Splitfire coilpacks around $600 depending upon how you source them.

Plugs are super easy, coilpacks come off to access the plugs and from memory they are plug and play also.

DIY approved!

^^^ Thanks mate i hope to have it sorted this weekend i will try just plugs first and see if that fixes it if not i will arrange for coil packs too.

You're welcome! DIY always starts with oil changes and plug changes and you try harder stuff from there. I'm a DIYer too.

There is a well illustrated guide on www.niztek.com (or .au?). I found removing the ignitor plug to be the hardest, but my car is a lot older

Cheers again, i didnt think it would be hard i have done DIY things before on my old car and friends cars but have not worked on a RB26 before. Thanks for that site too
