Hi Jim
I'm next on the list I think to have my injectors done. Mine's a 1998 V70 non-turbo 20v, B5254S engine. Its currently on 197,000 miles and I've owned it since 127,000 (6 years). Reading all these posts I'm ashamed of myself for not touching the injectors in this time! I converted my car to LPG 4 years ago also so understandably this hasn't helped the petrol injectors either.
By way of symptoms the car hesitates occasionally when cold (on petrol) and when warm I've had the engine management light illuminate. The fault code that is being produced is this one
http://www.obd-codes.com/p0172 "Powertrain: Fuel Trim System Rich Bank 1". I initially suspected either a faulty MAF or Lambda sensor, but now I'm thinking the injectors are the likely culprit. Can you PM me details of your address etc.? and do you have the type for my engine in stock?
Cheers,
Chris
