Hi Guys
Got a bit of a tricky problem that I can't work out
Last week went to Chequed Tuning in South Dandenong to get my car re-tunned for the first time in 3 years. He told me it was set very very rich, and that I was losing boost around 4,500 revs. We changed the spark plugs, then checked all the intercooler pipes to see if they where tight. They where.
Then is said to change the catalytic converter which I did it was really dirty full of black smoke (which was fuel). It is still loosing boost at around 5,000 revs.
Im going to ring mazda to check the oxygen sensor, I think this is burned out.
Whould this cut out boost?
Is there anything else it could be because I am stumped!, and it is not the solenoid on the turbo because I just replaced it.
If anyone can help that would be great.
Hope to hear from you soon.
