ENIGNE IDLE MISFIRE HELPPPPPPPP EP91 starlet turbo

I have a EP91 Glanza and am in need of some help!

I recently changed the acutuator to hks decat and already had a hks fuel cut defender I had the boost on a bar and set the fcd on 9

Runnin this for about a week

Then driving back from my local shops the car lost power no smoke or anything just was sluggish so when I got back turned the car off and back on

Misfire idle rev needle bouncing car shakes sound like a scooby but when u give it some revs it a little better still idleing but enough to move :/ ?

Any ideas

Been to the garge today to Cheak over I had the dizzy cap rotory arm changed plugs and spark plugs still doing the same problem

Injectors 1 and 4 work but 2 -3 don't took the rail pod swaped 1-4 with 2-3 but one and 4 work only so injectors aren't blocked then looked toward fuel rail there all working fine so now I'm stuck don't know what the problem is rilli annoyed now just want it fixed :( ecu ? Engine ? I don't know

HELP !!!!!!!!!

If the injectors are not working it will only be firing on 2 cylinders which is why it sounds dodgy.
Have you tried cleaning the connectors on the injectors?
What is your fuel pressure?

A compression test would be the first thing to do just to rule out any piston damage from running increased boost and a FCD.

Ye I have cleaned the injectors and fuel rail it was inspected and looked at it thoruly and he's lost ii rang a garage that sperlize in starlets and they said it was electrical but were to start :/ all the cylinders are firing and the pistons and that are all alright as it carnt melt them if there's no fuel coming though the injectors I'm so lost just want to get rid pissin me of that bad :mad: lol

@Collins611 - Are you the guy on Facebook that is running 1bar boost, FCD and no fueling mods?
Told you you would damage your engine that way.
Do a compression test as Texx says.

Would having slightly low compression on all cylinders cause a misfire? Sorry to hijack

Basically done a completion test it's fine loads of compression


It down to electrical apparently

I took the rail off to Cheak the flow of fuel and fuel flows though all fine
Then held the injectors on and only coming out of 1-4 then swaped the 1-4 to 2-3 so the ones that are working are now on 2-3 and the ones that wernt working or now on 1-4

Now it still comes though 1-4 :S witch is confusing

Don't suppose its my ecu

The plus cam of when the car was running one day and I put it back on while running would this have cause a problem I turned it of then back on bit ran perfect before the miss fire issue

But this misfire issue occurd 2 days after spiked ecu maybe ? I don't know

check with a volt meter if you're getting voltage to the injectors at the wire socket.
else try swapping an ECU from another car and check if it works.
i advise you to first remove the wire socket from ECU and clean the socket with a contact cleaner and plug it in and recheck before swapping the ECU.

your actually more likley to melt your pistons from running lean than over fuelling, although you've ruled piston damage out i thought it was worth knowing.

I had my engine re Cheak for compression and seems I have no compression what so ever in cylinders 2-3 ( head gasket gone :(. ) if I was to have the work carried out with this resolve my fuelling problem ?
Pointless doing the job then still run the same Becuse of no fuel coming though to cylinders 2-3 best thing to do is do that with a multi meter and ecu ?

Zero compression is more likely to be a result of damaged ringlands on pistons 2 and 3 rather than a blown head gasket. Best bet is to pull the head off and see what the situation is.

Zero compression points towards it being a little more serious than just headgasket as Texx says.

99% sure thats because you were running 1bar boost with FCD and no fueling mods.
Looking at your facebook pics it appears you have no FMIC either.
Still on the standard manifold aswell I bet...
