moosens Posted August 6, 2024 Share Posted August 6, 2024 MAF clean ? No air leaks in any ductwork ? Injector ? Link to comment Share on other sites More sharing options...
Steptoe's photos Posted August 8, 2024 Share Posted August 8, 2024 wasn't it this era that relied quite heavy on the input of the oxygen sensor? What does the injector spray look like ? Can you see it looking into the throttle body ? I might be in Australia, but I have had one of the spfi manifolds, and have feint memory of it.
