Right guys i was driving along in my car yesterday and my engine mangement light came on and i though Ohhhhhhhh no and then it started jerking back and forward (as if i had run out of petrol) anyway carried on then it was ok and then started doing it again !

I cant use my car now and obviously i need it big time !
When i put my foot down it stayed still then picked up speed as if the air filter was blocked

Any ideas on what i can do today to get it fixed ??

Petrol is low but not on red
Ive got a new belt (old one seems ok then) maybe worth a try ??
Air Filter hasnt been cleaned for ages but i cant see that turning the light on ??

HELP ME !

to reset the ECU, disconnect the negative lead on the battery, leave it disconnected for 1 hour+, then reconnect it.

not saying this will solve it though. Just a suggestion

16 pin diagnostic reading:
connect the XX with a paper clip and turn the ignition on, dont start the engine though!

0 0
0 0
X 0
X 0
0 0
0 0
0 0
0 0

every code is 4 digits long and will flash 3 times, if the light stays off then no codes are stored. If a code begines with a 1 then it is a vauxhall specific code, all codes begining 0 can be found at On Board Diagnostics.
10,4,10,10,10,4,10,10,10,4,10,10, is code 0400 EGR valve.
Hope this helps.

10,4,10,10 would flash 10 times, pause for 1 sec, flash 4 times, pause for 1 sec, flash 10 times, pause for 1 sec, flash 10 times, pause for 2/3 secs.
