Mr Noisy
Coming in your ears.
Well, actually it started misfiring yesterday, before I fixed the leak today.
Been laning for a few days, fine.
120 mile drive home, fine.
Took it for a jetwash, fine.
Drove it to town to pick something up, not fine.
Started this morning, moved it about, fine.
Once it warmed up, and I had fixed the coolant leak, it started missing.
You could blame the jetwash but believe me this car gets caked in **** and washed off again on a weekly basis so its not like it's a rare thing to jetwash the motor.
I've also had misfires before, this doesn't seem quite like what I've had before. Most times it misses on tickover, and really struggles to rev up.
This is more of a hesitation/stumble when you blip the throttle, but then it's not bad to drive and it's pretty happy to rev up to the redline.
I was thinking perhaps it's an injection misfire? Ignition is very precise, this is more of a half miss, i think. It just seems softer, not as acute. Not sure.
Anyway, checked coolant temp sensor, that's doing what it should. With the engine ticking over, unplug the sensor and it idles up, as expected. It seems to rev up better, less lumpy with the sensor disconnected. Plug it back in and it goes very lumpy again, not so much lumpy tickover but struggles to blip.
The fuel temp sensor however makes no difference plugged or unplugged. I couldn't find any data on fuel temp resistances, but mine seems to read around 1900 ohms cool and 1100 ohms working temp.
Any ideas please folks?
Im only asking this Q cos I don't think its ignition, seems different.
Interestingly as I left the garage before it drove great but when it got warmed up it went lumpy, although it still drove down the road quite reasonably. Drop a gear and give it a blip and it's all stuttery.
Hmmm, please help all ye experienced ones
