Gents can anyone help with this problem?

 

just got to work now, on the way in the engine ckeck light came on the last mile, also smoking and very rough idle and the cooling fan is on constantly??

 

i would hazzard a guess at the lambda sensor

 

i changed the chip back to the origional nissan one last week and the boost back to standard not sure if this had any affect on it?

 

any help greatly appreceated

Check the ECU for errors bud it should tell you what is wrong with it - there is a guide to checking it using on here somewhere I'll try to find it.

thats what im going to try to do in a bit if i can get out from work and give it a quick try

 

i do hope its nothing serious at all !!

Yep you've developed a fault which has put things in safety mode.

Usual suspects are the Maf, Temp sensor, ECU or chip.

Diagnostic will show yer the way.

 

Oh and you had a desoldered stock nissan chip?

Mmm..the only way the engine check light can be on at the same time the electric fan running is a corrupted eprom, this can also be due to a bad connection or short at the solder point or pins, the fact you have swapped the chip out confirms the diagnosis.

gents yes your right i do have a solderd nissan chip into a carrier, it was running ok for about a week and just today has given up, its running very very rich thats what the smoke is, and the fan is on constantly

 

i tried to do an ecu diag but the screw is split so cant turn it, is it ok to drive the car home about 5 miles, i have a conzult there i can plug into or even replace the jwt chip

It will run like a bag of shite, not known anyone to drive with a knackerd chip, generally it over fuels things.

I know i would lol

hey smithy your right its overfuelling quite heavy, im stuck on the nightshift tonight so maybe i could nip home to get the other chip to put in it to safely drive home
