Sweet thanks again for the help guys, borrowing a mates multi meter to check the leads tonight, after that i will be looking at the Fuel lines, make sure no kinks and then Fuel Filter. Can the Filter be checked or is it better off just to replace?

[leadfoot]

just replace man they're quite cheap

[Mopar]

Interesting to see the solution to this

[syco_rvr]

Hey guys,
tested the leads on friday night and they all pulled through with positive results

picked up a new fuel filter on the weekend and finally managed to fit it this evening, must say not the most enjoyable of tasks, however took if for a drive and still had the same issue. This being the case i was somewhat annoyed of it not running right so slowly built the revs and then gave it a a bit of a thrash, it gradually got better and better to the point that it is not lagging at all now.


So, i was thinking is it very common that the injectors could clog up? Might look to chuck some injector cleaner in with the next tank of fuel, your guys thoughts?

[leadfoot]

injector cleaner in tank is next to useless pull them out and have em cleaned properly will net far better results

dont take this the wrong way mate....you have done the basics and had a small win by saving some cash. I suggest you now take the car to someone with proper diagnostic equipment before you run it so lean that it shits itself

Advice taken finally got around to it and dropped the car in this morning. Will be hopefully picking it up tomorrow morning all going to plan, and will pass on the news when i can, mechanically speaking i hope its not something small but speaking from the wallet i also hope it is haha

[evo-gsr]

Good advice Brian...and good on the OP for listening to the wise words.

[EvilRacer]

My bet is a air leak somewhere. Possibly even in the exhaust manifold, but most likely a hose has a split and is only opening under higher loads.

[evo-gsr]

All will be revealed once the owner picks the car up in the morning, Im guessing !!

[syco_rvr]

So turns out the ignition timing was out, thankfully the guy that was working on it had previously owned and evo 1 so after going through what i had already tested/replaced he came to it pretty quickly.

he mentioned that if the battery goes flat the timing can like to reset itself? anyway runs a lot better and even comes on boost more aggressivley than before.

thanks for all the help guys

[jack be nimble]

Otherwise I know if timing is out and I put foot down it can bog right down and take a long time before it starts climbing the revs. Probs not what yours is doing but the thought Is there

Here's a dedication song to you my dear jack

It was a party night, it was the end of school
He's head was feelin' light, the first time
She seemed much older then, she had turned seventeen
And she knew some older men, the first time

Come said the boy, let's go down to the sand
Let's do what we wanna do, LET ME BE A MAN FOR YOU
Oh-woh-woh-oh, oh-woh-woh-oh
Oh-woh-woh-oh, oh-woh-woh

And she said
Well I've been waitin' for a long time
And you've changed a lot
Up till now it's been the wrong time
To know whether to come here or not

Oh, now come with me boy, just take my hand
I'll let you see what you wanna see
Come on, be a man for me

Hoh-oh-oh, we've both been waitin' for a long time
We've both changed a lot
Up till now it seemed the wrong time
To know whether to come here or not

Oh, but come said the boy, let's go down on the sand
Let's do what we wanna do, let me be a man for you
Just say come with me boy, just take my hand
I'll let you see what you wanna see
Come on be my man for me
Oh-woh-woh-oh, oh-woh-woh-oh
Oh-woh-woh-oh, oh-woh-woh

It was a party night (oh-woh-woh-oh)
It was the end of school (oh-woh-woh-oh)
He's head was feelin' light (oh-woh-woh-oh)
It was the first time (oh-woh-woh-oh)
She seemed much older then (oh-woh-woh-oh)
She had turned seventeen (oh-woh-woh-oh)
'Cause she knew some older men (oh-woh-woh-oh)
For the first time (oh-woh-woh-oh)

This thread has suddenly turned a bit gay....
You guys need help I think

[111GSR]

Thread hijack, (in hope to remove the gayness lol)

Last few days started getting similar symptom. Under boost car is beginning to stutter as if running on 3cyls. However boost reaches full 10psi (stock setting).

- Pulled out plugs (only 5k old) all looked fine, good gap etc, bit on the white side but nothing drastic.
- Replaced ignitor with a VR4 unit.... no change.
- Replaced coils with VR4 units.... no change.
- Checked leads (only 5k old) all good.
- Replaced 310cc injectors with 450cc injectors just to see if 310cc are faulty/dirty.......no change.

- Tomorrow going to test for fuel pressure reg condition/operation... If checks out fine will replace the fuel filter and pump.....

[jimmyratsbreath]

Finally getting back on track.
I had severe lagging and yes it was a timing issue.Recently it started to return and as you stated I also pulled out my plugs (under 5k old) and they looked good as new etc. Anyway threw on a new set, problem solved.
Both sets were NGK.On a scooter forum I go to in England they seem to have quite a few problems with counterfeit NGK plugs over there .
