I recently left a post on a thread wich was about a gtv missfireing as it had the same symptoms as my spider. It had a reply or 2, but as I was on an iphone on 3g it was tricky to use, and now I cant find the page.
At the time I was stuck up in north wales climbing, and am now back in cardiff with proper internet conection so can start my own topic, to try and get some answers.
The problem started about half way up. And only lightly, when pulling away from traffic lights, roundabouts etc, it would slightly miss fire, maybe pop, but would soon clear as the revs got up. But it soon started continualy missfireing as soon as there was any load, and would be a continual rough ride, as it was seemingly not running on 1 cylinder. It was back firing, and the missfire almost felt like it was holding back, something needed to pop, clear it, and fire up the cylinder, with momentary sparks of life. but mostly farting away. and the power was rubbish, it took ages to get up to speed and there was no chance of over taking. I think it was ok at idle.
This lead me to think it could be a coil pack not getting enough power to a plug!? Any thoughts? and if so how do you go about figuring out which one?
On the way back donw it seemed ok for about 5 minutes, maybe until it warmed up. And again it was rought, but after a while it was similar, bad under initial load, pulling away etc, but when the revs were higher it would clear, and respond a lot better. But as I say, if you put your foot down in a higher gear, it would miss and judder, backfire, so drop it down a gear, and some more revs would sort it out. At least the journey was better than the way up!
Any help on this would be amazing, anyone had this problem!? As want to get it sorted myself, dont really want to fork out loads, just for a garage to poke arond for ages trying to figure out what it is. Or would it be a simple job for them, like plugging it in? A bit skint at the mo, so just want to buy a part and sort it.
Possibly a lambda sensor? coil pack? plugs?
cheers for reading this essay!
