Hi

Can anyone help with this,

I have had my injectors changed and they are still flooding cylinders 3 and 4. it runs ruff or dosent start. mechanic wants to change them again, i think its the computer, but he is sure its not. im not confident its the injectors the second time round.

I have replaced the fuel pump, and electrical has been checked theres spark, mechanical is ok as well.

Is there anyhting else i shoud be looking at such as sensors ?

Fuel pressure regulator, that's about all that pops to mind at the moment. It pretty much has to be that the injectors either stick open too long or are shooting too much at each firing. Were they replaced with new ones or refurbs or what?

Injectors are leaking because they weren't installed properly. Make sure the o rings have been replaced and lubed properly when installing the injectors.
