Fueling Fundi's

What would be causing that ? I am also still convinced it is a fueling problem , but where do I start looking ?

It would be good if you can compare the afr between cold and warm. The fact that your car revs to 8000rpm worries me.

Why would it worry you ? I have taken her up to 8500 when she wasn't cocking me around .

In otherwords , what is going to break ?

ja the CA redline at about 7600 and the SR at 7200

do you have a piggyback on your std management?

Breaking doesn't worry ,but the thing that does is the lack of a rev limiter before 8k.

It is a stock S13 , except for the 76 mm freeflow and air filter. It was maintained by the Agents up until 150 000 and the guy I bought it from had it up until 158 000 , so I don't know if he did anything. Judging by the semi mutalated Sabre he was driving , anything is possible.

I'm not sure where the rev limiter should be but if its gone there could be some after market chip attached to the ecu which could stuff up your fueling.

I can appreciate that , but the car was running perfectly up until about 3 weeks ago.

I think the best is going to be put it on a dyno and see if it is running lean or over fuelling or if it is losing spark.

what do you guys think ?

Sounds good.

1=check all vacume hoses they do pop off(there where the turbo is and the littel bugger behind the head)
2=check coil packs one is on its way
3=afm is maxing out

when its holding back does the car miss and then its like boom its gone and coz when my coil pack went it done that

Exactly like that. It misses a bit as if it's holding back and then it pulls like a demon again.

then i will put my money on a busted coil pack
but just check all vac hoses coz it can do the same thing
try and borrow or buy some spare coils and change them out

you can test the coil but its a bit shocking if you make a bobo while the car is running un screw a coil pull it out a littel bit and check how strong the spark shoots .all 4 must be mostly the same but if its very week its fukt

dont drive the car to hard with busted coil coz it is over feuling the cilynder with the busted coil.from when it started has it gotten worse and hapening
more often?

Yeah , it is happening more often and when it holds back it feels like the hanbrake is up now. Today so far it is running okay. I have only felt it once or twice , but it is definitely getting worse.

then check the coils verry soon when its hot its gonne start missing and going to stay like that then when you park and it cools its gonna start normal again.
also notice when it does does this when driving park and smell the shit load of unburnt feul in the zorst

If I must be perfectly honest, it sounds like you have been driving my car !!

LOL

Everything you are describing sounds spot on. The smell of fuel , I put down to the 1 injector that has a very , very slight leak. I thought that was what I was smelling, the bit of fuel on the intake manifold.

So , now the fun part , cost of coil packs + - ?

Thanks for your assistance

I must also add that it only misses under load / boost . Normal driving she is fine.

Would a 200 Sabre / Sentra coil packs work ?

just for safety check the vac hoses the buggers do pop

can only use ca18det coils there is 4
sentra only has 1
at nissan coils is like R1000 each
2nd hand R200-R500 each
keep an eye on the problem if it gets worse when hot and try fix it asap
before BOOOOOOOM

Will do , thanks

Coils at nissan are R1400
