Hi, symptoms are as follows:
- Car is fine when cold, runs normally, albeit poor MPG
- Car is fine after even 15 - 20 minutes after starting from cold however shortly after this there is a misfire that seems to disappear under hard acceleration.
average mpg is down from about 23 normally to 13/14. It appears to be over fueling, replaced the plugs today and the old ones that are about a year old were badly fouled with sooty deposits.
Does anyone have any ideas what the problem is? There are no codes to be read.
Compression is also good- was tested 4 or 5 months ago for an unrelated issue.
