Hi Scotty I'm a big fan thank you for all your advice its helped me alot, my wife has a 2003 lancer oz rally she popped the timing while in motion I sent the head to the shop and reassembled I got a p0300. Since then I've come to find the maf sensor to be defective (bought from amazon prior to belt pop) i chased it hard changed fuel pump injectors map sensor cleaned egr added fuel gauge pcv o2 sensor fuel presser regulator alternator starter positive engine cable till I saw it was maf defective. I still have a hiccup fuel rail for sensor 1 bank 1 drops voltage randomly and I can't figure it out any more advice? {black}:idontknow:
I have a graph picture from the app torque pro shows what i mean, how can I send it?
Couldnt figure out how to attach files here google didnt help ether so I uploaded it to a site here's the link https://ibb.co/0KPjLMh
Its throwing lean code sensor bank 1 I think I need to revisit egr and check for some kind of air leak? P0171
