Went to get the car out the garage today for the 1st time in a few weeks, and the car wont rev no more than 2800 rpm (when the turbo comes in) soon as it his 2800rpm the red light on the dash comes on and the car goes to stall .............................then the idle valve keeps it alive.



Does anyone know what is causing this

Cheers

witch red light

 

Theres a light on the dash with a picture of a engine ? warnning light!!! It wont rev above 2800rpm

 

sounds like it's a boost problem and engine management is closing it down(safe mode) start by checking ALL connection,amal valve and ecu plug at a guess!

 

Erm whats the amal valve mate and where is it located

If it's still there and your car is standard spec it will be on top of the i/cooler!

 

3drs have an engine management light in the dashboard!

 

 

no need for that m8 as EVERYONE can learn something new every day

 

 

Yeah its only stage 1, so it still has that valve , if i disconect it i can hear a clicking, why the car is running that is .................... How do i test this

What else ??????

 

Hi mate,ive looked at these today and everything seems normal. The car starts fine and runs untill you hit boost then the rev counter drops too 0 but the engine is still running,hit the accelerator and the rev counter jumps to idle again , even tho the red light is still on ???????? Basicly i can drive the car but cant go above 2800 rpm or it jults and the revs drop



HELP

 

IS the above from cold or from once cars warmed up?

take the dissy cap of and have a look at the phase sensor condition of the wires and the size of the gap!

 

Dont matter if its hot or cold its still the same ive put another map sensor on it and it didnt change anything , just got to look at the phase sensor now

 

All is ok, i really duno where to look next

 

check the tps sensor and also a try another ecu L1 or a L6 one out of a saff (with a standard or stage 1 chip) WILL do just to try out straight plug in with NO other changes needed!

 

Just been out there again,from cold it was ok, soon as it warmed up reved it up loud pop from the exhaust and ON came the red light ,it has got a L6 ecu from a saff I will see if i can get hold of another ecu this week, if that fails im going to burn it

Thanks for your help alvyn

 

Have u tried the water temp sensor on the passenger side at the back of the head.It sud b a blue connector a bit of a pain 2 find u have 2 take the hose off to get at it.

 

Yeah ive changed that too !!! would this cause the red light to come on?? been told ...........throttle position sensor ?????????????? How do i test/remove this?

 

change the coolant sensor 1st m8!

 

Done that alvyn ,ive sent you a pm !!

 

had the same problem, changed every sensor but didnt fix it ! it was the ecu , tryed 3 level 1 ecu's but couldnt find a good 1 ! so used a level 6 , it cured it straight away .

 

Mines going to be sorted tomorrow, as i aint got a clue what else it could be ,should have it back by the weekend


Thanks for all the help !!!
