injection noise/nailing
injection noise/nailing
It has been getting worse to night I replace some collapsed leaking fuel supply line and filters and it stopped nailing almost completely!
So I thought I would crack each injector to listen for any noise! If I crack cylinders 1,2,4 the car will slow down and Nail really badly! If i crack # 3 it slows down but no noise nailing
If the engine drops even slightly below idle it starts nailing really badly on #3
I'm going to swap injectors this weakened and see if the problem follows the injector or if it stay my guess is a weak injection pump.
As rebuilding the injectors and doing a valve adjustment hasn't changed it

Like 30 Years old!
Prolly could well do with replacing the nozzles and re-setting up....
No point on earth in just cleaning Old Injectors.....

This weak end I'm going to swap the known nailing cylinder's injector to figure out if its the Injection pump of the injector!
If the nailing changes cylinders its the injector! if it stays it's not the injector!
