well guys dont if this is the right place to start.

her is the problem:

car starts and goes off sudenly, after aome tries starts and engine revs properly after ome time the rpm goes less than 1rpm and then when press the gas padal the rpm goes till ""3 rpm only"' it goes struglling. then is switch the car off and start it again it is fine . then when i m driving the rpm goes less than 1 rpm again, some time it dosent, but i when evr i go more than 4rpm the car cuts off and rpm goes less than 1 rpm.


well i got turbonetics single turbo.

waiting for ur reply like hell.

 

Sounds like its in limp mode.. Maybe you blew the engine with the TN.. Have you tried to reset the ecu or read any codes?

 

Might be detontion. I used to have it on my Mazda with the same simptoms.

 

hi bro how do i reset my ecu. and is it safe to do myself as i dont know much about ecu. and how can ired some codes do i need some professionla equipment to do that and what is this detention.

more response plzzz

 

All you have to do is detach the battery for a few hours.. It will reset... Or do this.... http://www.technosquareinc.com/350reset.htm

To read codes you need something like this... http://www.sears.com/shc/s/p_10153_1...0070921x00003a

I think chopperman means to say DETONATION.. http://www.cartuningcentral.com/what-is-detonation

Not detention.. http://en.wikipedia.org/wiki/Detention

 

Jay thanks for the spelling check. OP yes I ment detonation. If you do not want to get a code reader go to autozone/pepboys and they will read the code for free.

 

Do they have Autozone in DUBAI?

 

Lamo.... Mybad didnt see your location. Isnt Dubai ballin with nice cars. Go to some tuner or something

 

thanx for ur reply guys. dubai is having gud cars , gud tuners. but they r in dubai for money so wat they will start from spark plugs and i dont have xtra$$. cuz i think i have WWW.My350z.COMc

is there anything to do with harness or throttle body or throttle sensor.

waiting for replies.

 

Go to that technosquare link i posted.. Thats the only thing i can think of...

 

Follow the instructions in the Technosquare link Jay-Z sent you to do a TPS relearn. The strange thing is that your problem seems intermittent, usually once you are in limp mode it stays that way until you fix the problem.

Did you just install your kit or has it been running trouble free for some time?

The codes may be important here, you may need to buy/borrow a code reader to better diagnose the issues.

Jay-Z types faster than me.

 

well i will try the tchno thingi first.

the turbo has been running proper for almost a year . i bought the car 2 months ago but never had this problem.

starting is only some times but i can never go beyond 4500 rpm they car just cuts off and rpm comes les than 1000 rpm.

 

How about getting a scanning device and checking the codes?
Since it sounds like you having to troubleshoot on your own, then something like the Cipher tool would be invaluable to you. It can help you quickly figure out the problem: http://www.forgedperformance.com/store/home.php?cat=447

 

^+1 Cipher is invaluable for diagnostics on a FI car.

Vacuum leak or bad (dirty) MAF are the 2 things I would check straight off. Cipher can tell you exactly what the MAF is reading.

 

Yup pull codes like mentioned and then start simple.

Check plugs first (had similar symptoms on a Z31 turbo with burnt up plugs), then check all piping from turbo to TB, and all vacuum lines.

It sounds like your MAF is disconnected or installed backwards or there is an intake leak. You'll need to check that and then reset/clear codes to get outta limp mode.

+1 on the Cipher!

 

guys will try evry thing and let u know by monday. thanx alot for ur response.

 

sorry guys for late reply as i was busy wid uni.

hi jay z i tried the reset thing but that helps me for little time only.
