This on behalf of a m8 from Corsasport.co.uk..............
Corsa sri 1.4 8v, k reg, 81000 miles
My car 2day started and ran as usual... however after 2 mins i see that the temperature of the car was 95ish and just stayed there.
through-out my 12 mile journey 2day, the temp. was rising and falling way more than wat you would expect!!!!!
The more i drove it 2day, the more lumpy the revs were and the car just cut out on me (for no reason).
I had this problem over x-mas and seemed to solve it by cleaning out the pipes leading to the rocket cover (coz they were full with crap) however i had a quick check and they were all clean 2day.
Wat I think it is?
could it be the cat or the mid section exhaust pipe....(would it cause a build up of hot flumes in the manifold or something - due to the pipes being blocked)
Also to add... i did take the car for a long journey yeasterday and down the motoway (on motoway for 15 mins), I took the car up to 4.500 rpm.
PLEASE ANY1 WITH A SUGGESTION!!!!
found this on the net-
"Indeed with engines equipped with a Map sensor for calculating the air flow, the engine vacuum is even more important since a lower than normal vacuum causes the electronic control unit (ECU) to overfuel the injectors."
so mines doing the opposite....the voltage is high so in theory thd ecu is UNDERFUELING the injection therefore cuts out.
is this right???
