With my VERY limited knowledge it sounds like it could be a MAF issue?
You are absolutely spot onYou remove the air intake pipe at the throttle body then remove and clean the flap and the inside of the air duct that the valve is in you ca see it once you remove the air pipe.:thumbs:
Use some carb cleaner or brake cleaner?
Some times the dirt build up can stop the flap closing properly allowing uneven airflow or insufficient air causing the idle to be un even.
Hi gapfhild, I have carried out pretty much the same work and checks as you have. In addition I had the O2 sensors changed and a full service. I still have some erratic idle but alot less and this disappears completely once the engine has warmed up which is pretty quickly. Overall the engine is running very sweetly and is very willing to rev. I am thinking of adding a RAMAIR Maxflow Induction Kit and, possibly a Ragazzon Stainless Steel Sports Exhaust sometime this year. An excuse to see if this improves the running more. Let me know how you get on.Hi, did it solved your problem?
I have an Alfa GT 1.8 TS (38800km)with the exactly same problem. Here is what I have done to try solve it:
- New spark plugs
- New full-kit Distribution
- New intake air filters
- Oil Change and filter
- Throttle body cleaned
- Injectors cleaned
- No past errors found in ECU
Until now, no good. All of this was done by Alfa Romeo support. Please, if you found the solution, describe it here.
Thank you!
