92 VP exec 3.8 sII
This morning, the car had troubles starting, I ad to try to turn it over 4 times and when it finally fired it shot to 1600rpm, dropped to about 750 (my idle speed) and had big difficulty maintaining it.
Driving, the cabin eventually stinks of unburnt petrol, I have an intermittent engine light and just pretty slow foot response
What could it be?
What is the engine light for?
... It's there to notify the driver there is an issue with the engine?
If you mean what code is it giving me, I have no idea I don't have an OBD kit, nor the 'can be bothered' to bridge the connector.
My friend suspects it's a leaky injector(s) Because it has difficulty starting after it's only been shut off recently, so the fuel is leaking into the cylinders and not firing right,
And when it does fire it shoots to high revs to burn off the excess. Whereas starting after it's sat for a while the petrol evaporates and therefore the cylinder is empty. Also explains the strong unburnt smell.
My theory is this: I only recently put in a full tank, since owning the car for 2 years (lol don't ask), so all the gunk inthe tank shifted and got sucked into the injectors and clogged them, hence the leak and the above problem.
Should I try That nulon crap or get them professionally cleaned and redone. Maybe get the spark plugs redone too, it's been a while I'm assuming they're near fouled.
Dont bother with that nulon stuff. Check your bloody codes and get your rad fixed and get back to us.
usually the cel means you should find out what the problem is.
logic dictates that when a car runs like crap you'd put the effort into finding out also.
ah well, as for a 37 degree day, you turn the ac on and sit in comfort while you watch the flashing cel......
I was right, the injectors we slightly blocked but they cleaned themselves up with some flogging. and confirmed with a mechanic injector issues will never show up an engine light as no sensor in VN/VP can relate to blocked injectors or really anything fuel related
As for the radiator, a return hose gave way and exploded while driving, was inevitable because the rubber had gone manky.
She's gonna be off the road for a few days
well there is one sensor that'll log a fault and another that'll give it away if you log data providing everything else is in top condition but we'll not mention those, your mechanic might learn something, what error codes was it showing?
and ok, you'd run the car with the ac on then get in after it's nice and cool and hopefully you parked in the shade to watch the pretty flashing lights reading codes as per my last statement.

I didn't check the codes but as I said before none can relate to blocked injectors there is no sensor inthe car to actually check the cleanliness of an injector.
The codes showing were related to the pressure in the cooling system Being erratic, the pipe exploding was an unrelated issue
code 13 and 45 might just be a hint
fuel reg on the rail will cause hard to start, idle issues and inability to maintain idle. and will cause fuel smell in the cab if fuel has been making it's way into the vacuum line from the fuel reg.
wont usually show up a MIL/CEL though
