engine bouncing around - Drifting forum

islander · 14-05-2008, 10:37

Just started the 200sx up after 2 weeks of non starting as moving house and no tax and it is playing up.

it seems like its starving of air or something.

i cant describe apart from the engine is shaking more than normal like its bouncing out of the bay lol,.

I think it may be missfiring but i dont know how to check apart from that i dont know what it is.

anyone have a guess at what it cud be then let me know as mot is friday

islander · 14-05-2008, 11:52

Carta · 14-05-2008, 11:57

My money's on Coilpacks

MJG · 14-05-2008, 12:17

My engine bumped when missfiring too, turns out my HT leads were on the wrong way round lol. Yeah coilpacks regularly go on them and they are easy to swap.

What does misfiring feel like when driving?

MJG · 14-05-2008, 12:27

Like the car jerks and doesn't pull properly and sometimes pops and bangs randomly, and sounds less smooth from the exhaust as it is not firing evenly.

Carta · 14-05-2008, 12:29

It definatly sounds less smooth from the exhaust when Idle, but not noticed anything when driving. Ill have a drive and report back

islander · 14-05-2008, 12:38

found the sparkies, the second spark plug has water around the bolt part of it, gonna remove it when i find my tool in the boxes after moving.
keep you posted.

MJG · 14-05-2008, 12:45

That sounds like it could well be the issue Islander, good luck with it

Hopefully will be a nice simple fix. Make sure you don't get too much water dribbling into the cylinder if possible, use rag to dry it out before removing the plug. Then use WD40 or similar on the plug and the connectors etc.

islander · 14-05-2008, 12:55

thanks pal, i will do just5 that. got to find the sparkie remover first

Andy_f · 14-05-2008, 13:37

Just incase you happen to get any water or shite in the cylinder, just pull the fuel pump fuse and crank it over for 20 secs or so without the spark plugs in, and it will blow any shit in there out of the top.

islander · 14-05-2008, 13:45

still cant find my tool for sparkies, and thanks for the advice andy that will help and stop any other problems popping up.

Carta · 14-05-2008, 14:15
