:( Wont Start!

[chrissyo]

Hey guys, recently my r33 gtst series 2 has started to stuggle a lil on cold starts. Revs fluctuate a bit but it sorts out and idols fine then all is good

Ive also noticed that the last week or so ive been getting exhaust soot on my rear bar? im not sure if this is all related or what

Tonight i went to go out, car started stuggled a lil like it has been but was then fine, drove around the cauldersack before the car started to jolt and stall!

Now when i try to start it the engine cranks over revs to about 1100rpm then cuts out. Sometimes it will rev a bit /\/\/\/ but then cut out still?

Im not sure what the problem is tried searching but couldnt find a similar problem.

Please help guys

no need to reply! got it running this morning, somethings up with the AFM. About 6 weeks ago i re did the dry solder joints and its been running fine ever since.

This morning i disconneceted it and the car started fine first go pluged it back it and now its working??? not sure if it just wasnt plugged in properly at first or not?

i imagine if that was the case it still woulda started though(considering it started when i took it out!!!) Will just have to keep an eye on it.

Cheers

lol first thing i was going to say was afm related, clean it with electrical contact cleaner, then prehaps check the solder joints.

cheers.

Ok so car is not good as i thought! wont go, starts drives a bit and revs are just all over the show.

I redid al the solder joints about 6weeks ago? ive just taken it out and im looking at it atm and it looks fine. all the joints are nice as!

what else could it be? spark plugs? :s sorry im a newbie

Cars now starting without the AFM in it...but try driving and it jolts when u get anywhere near 2000rpm

the car wont let you go over 2000rpm if you unplug the AFM.

give it a clean with contact cleaner and see how you go.

[chrissyo]

do others agree with b1 mr fanny?

i need to get some contact cleaner 2moro. The car actually gets to about 2500 before it starts to 'misfire' not sure wat word to use for it. So is that how it works? when the afm isnt in the car can start but not rev over X? it starts fine without the afm everytime. starts with the afm just struggles more but in both cases u cant rev over 2500

Wells just thought id let everyone know that i gave my AFM another clean! redid all the solder joints again. this time it seemed to actually work!

cars now running better than ever in some ways atleast

With the afm back in its starting fine! Not sure if anyone saw my other thread but ive had troubles with the car backfiring over 5000rpm....afm fixed that.

And now it works sometimes and sometimes it doesnt!

Had to pull over 3times on the way home tonight in the space of 10km

Ordered a new AFM hope thats all the problem is

usually you will get a fluctuating idle, try cleaning the AAIC valve which is on the back of the plenum.
