Car: R32 Gtst manual
Mods: Only has a high flow turbo and a cat back exhaust
Situation:
Ran car hard on empty, had no option to put questionable unleaded fuel in – Ever since doing this, have had major problems with car.
Symptoms:
Car has always been hard to start cold, however ever since running car empty and filling up with unleaded, when the car starts it has a lumpy idle (until at operating temp) and wants to stall when pulling up to traffic lights (but doesn’t).
Car also feels like I am towing a trailer and once it hits operating temp you can feel a surge and almost like a weight has been lifted from the car. Coughs, splatters and honestly feels like I’m driving a car with untuned webers – Until operating temp.
I have since been running the normal premium fuel (normally Shell) and still runs like rubbish – I had in innocent in Brisbane CBD where the car stalled and would not start – Blocked filter perhaps?
I have changed the filter and have been running injector cleaner for roughly 200kays – It now has no issues at all at operating temp, when cold is another story.
The fuel filter that was pulled out of it, was full of gritty sludge (understandable), I have had a few suggestions:
- Grit has damaged injector? – Doesn’t explain why car works at operating temp
- Has got water in the tank from rubbish fuel – Doesn’t explain why it works at operating temp
- Stock BOV
- ALL factory recirc and return lines are in place
- AFM has been replaced with known working one
- Plugs are in working order
- Fuel pump is in working order
- New fuel filter
- Only ECU error code is throws is something re: auto (Car is converted to manual)
Any insight into my shitbox would be great
