Help
Alright well i picked up an mk111 7mge for 1000$ a couple weeks back and when its running it runs good, but it has a really unreliable start. i changed the oil and oil filter, put in ngk sparks and wires, changed the igniter and coil pack and switched to premium gas, and ran techron through it, The car seems to be carbon fouling, also sometimes it will start cold but it seems to hate starting hot, if it stalls or if you turn it on it wont start back up, its a rebuilt engine with only around 1500 miles on it. i ordered a new fuel filter which im waiting on now because it had been sitting for a while, but idk what the problem could be, can anyone help?

Please use descriptive thread titles
probably killing it with your premium gass. you don't need to run it. Once in awhile won't hurt.. but your actually doing more harm then good. first thing to check when buying a car is any stored codes? do a dio.

freind had a friggin mazda that did this too me once. we replaced the plugs and wires, fuel filter, and it still did it. we were baffled, cuz it would run just fine. then it quit altogether. we took it too a shop and had it diagnosed. it was the damn o2 sensor....that didnt make sense to me, but we replaced it and it still drives to this day.... darn ford...

yeah i know they all should, but the person before me changed out the stock headers and downpipe which relocated the o2 spot to right before the cat, but he blocked off the o2 slot will like some steel sheet, and then he might have cut the wire
