After a year of ownership my car has just started to give me a headache.

Its hunting for revs at low rpm. When I go to pull of at a sedate speed round town it stalls.

Its now also stalling on start up and gets very shaky when the choke cuts out.

Now all I can think of is that the maf is failing or the amp I've got connected up is pulling to much and killing the altinator.

Cheers
Simon

 

Have you tried the MAF/lambda tests (click here for help)...?
