180sx Idle's Like A Wrx!

[shook]

Just got a 180sx that has been sitting the garaged for about a year or so ..

- Had old petrol in it ..

- Had old oil in it ..

Test drive - perfect - fine nothing wrong with it

Driving home - fine nothing wrong with it

Started to act up nearly on the way home for some odd reason, it starts shaking like a wrex in first gear.

Mods, just basic mods. Pod and thats it I think ..

What i've done to it since i got home

- Drained the raditor fluid

- Drained the oil

- Poured petrol in the car

- Changed the oil filter

- Poured the fuel injector cleaner liquid in..

Problems

Where you pour the oil in the engine, when you open the cap smoke comes out of it ..

The car idle's crazy, but when you start it up its fine, then starts going all wierd.

UPDATE:

well - when i start it up sounds fine and reverse and everything, but as soon as i put some presure on the go it starts shaking and stuff again. sometimes when i start it up it shakes, sometimes it doesnt. wierd stuff..

sounds like one of your coils is f**ked, which is making it run on less cylinders, my 33 did this after i washed the engine bay ( i think i got one of the coils wet). i just tested it, and then replaced the coil and it was fine. im not sure as to what resistance an sr or ca coils are supposed to have.

yep

you either have a f*cked coils pack or youve dropped a cylinder

well the car ran fine like the past two days and just started to act up again.

i think i just need to clean the sparkies or get some new ones.

but im getting some second hand coilpacks to change em anyways. should be fine after that

thanks

[**JaR**]

wasnt this same thread on NS??

neways.. my guess is coil packs...

[shook]

yeah just tryin to go around to different forums and get different ideas before i do anything majour about it..

[shook]

today i just pulled out the sparkies and coilpacks..

somewhere there is an oil leak and the oil is all over the sparkie and coilpacks.

what should i do?

[shook]

just changed the spark plugs and when i started up the car it sounds like an angel ..

but im still going to change .

- new valve cover gasket

- second hand coilpacks

ahh this is happening to my mates car atm. r33 series 2 gtst. thought it was coilpacks as well.. we tried unplugging the coils one at a time to see which was the stuffed one.. but all of them were the same..

shoudl we assume his engine has dropped a cylinder?. the car is pretty weird.. it sometimes revs on its own lol.

You would know if it had dropped a Ring/Cylinder...

Same thing was happening to my mates RB20 revs were constantly fluxuating...
