So you don`t see this often, ConZult screen shot below from a Jap spec TT with a slight running problem (backfire, will reveal later) any thoughts or theories?

Cam shaft worn or valve not seating fully

Dont tell me, the injector was firing when the valve was closed?

knackered valve spring causing one of the intake valves not to seal properly?

VVC solenoid

I would say injection on to closed valves due to timing belt alinement

Dont tell me, the injector was firing when the valve was closed?

 

Effectively yes, there was a degree of overlap caused by the bad cambelt timing, but also there was a faulty earth return on the afm plug causing a corrrupted signal to enter the ecu, this in turn was keeping the injectors firing non sequentially, a simple repair.

these threads are awsome

they help everyone

keep em coming

Well with out being near the car, i wouldn't of known about the faulty earth return lol

 

Also grats on passing the 2k post mark (might even be the second time lol) but grats anyway :D

Take your point, this is exactly the issue we have with phone call tech help anyhows you guys are too clever so have to hold a bit back :D the point however I should have made clear is there is no actual genuine fault on the zed that can produce injector leaking error code, so its always a corruption error, so even if you had a leaking injector this code would not pop up, fault diagnosis can be very tricky.

 

2k mark well I seriously did not notice!! second time around......probably:rolleyes:
