Im puzzled

Hey guy's i have had many problems recently with my new s/h VTR its cost me £1000 and i have only had it nearly 2 weeks,

My engine management light constantly comes on it has been in gargage for this problem 3 times uggh 1st time they cleared all faults and said it was suspect coil, the light came on an hour after i picked it up, took it back and got the coil fitted light came back on again after an hour waited till next day to take it back to garage and the light didnt come on when i went to take it so rung them and cancelled, on my way out that evening the engine management started flashing yet again and started to create a shudder when i accelerate but as long as the light aint flashing and is on constant its fine took it back to the gargage and they are stumped they do not know what it could be as the computer is not throwing anything up any ideas??

i would change fuel filter first,

[Ramsay84]

would that cause the management light to come on?
My exhaust also fell to bits today from the attchemnt at the back box and middle section would that cause the light to appear?

[gaz4399]

not sure if that would put the light on.

the exhaust would not put the light on

i would just check the basics such as fuel filter and plugs to start with

someone told me this could be a problem with a air pressure valve?? what you guys reckon could this be a problema and would it light up my management system? also how much would somet lie this cost??
