Misfire, hesitation, but allllll the spoool
Posted 03 May 2014 - 12:55 PM
Started cold and everything was sweet.
Rev a bit after a couple of minutes and it starts misfiring. Yay. It's Still drivable but it's frustrating. Sounds like a wrx. Not cool.
Put some new petrol in and check for spark. All good. Can't find any vacuum leaks either...
When driving it really hesitates but the turbo spools no worries. Then suddenly it seems to launch. Any ideas?

I reckon spark leads. similar thing happen to me except mines a NA
new leads fixed the issue. or could be the dizzy

The fact that you said it sounds like a subaru led me to believe it was a spark issue.
What about the fuel filter?
Are you loosing power when it sounds weird?

Still sounds like a boost leak to me.... do you have a boost guage?
Posted 07 May 2014 - 11:16 PM
Yes to boost guage also. It seems to be boosting fine, almost to fine for running like shit.

AFM could be shagged, mine did a similar thing but when engine was cold, not hot. Might be worth a try if someone else has one you can borrow
Had two people on seperate occasions ask if my car had a rotary engine in it thats how bad it sounded lol

18-22psi vacuum as well(or any noticed difference)? If not then rule out leaks.
Can you try running your finger underneath the distributor along the edge of the cap? Any oil on your fingers?
Have you checked the inside of the cap and rotor?
Checked codes? This should show issues with AFM, O2 sensor, ignition circuit, etc. Always a good starting point.

Haha. Glad that 20b is getting some use.
I'd say the oil is causing the problem. I had the issue with my car a while back, where it caused severe missing to the point where it would stall at idle. Some throttle would bring the revs up and stop missing but it would lack power and miss under load. I rebuilt the dizzy and no problems since. I'd recommend replacing the rotor and cap at the same tip

While the turbo was off I had studs removed and a few helicoil a put in the head, starting to think I should've just done all of them.

I'd say try and get that dizzy rebuilt and if the problem is still evident go from there. It will need to be done anyway if it is leaking

That's not good.... just go to the wreckers and pull some out of another driveshaft....

Actually I in recent memory had a VERY similar issue on my N/A ST162 we tried leads dizzy etc etc, turns out the injectors were blocked. When they were cleaned it felt like a totally different car and fixed the issue. I do find issues similar to this is a tad overlooked, mind you my car is N/A not turbo so I Could be wrong

i fixed it a while ago, stupid old injector clip was brittle and old and in the process of me taking them off when doing the clutch a piece broke and got wedge underneath somehow preventing solid contact. i was ready to kill people. id dont he dizzy and leads, discovered the power steering idle up canister had snapped off a vacuum line so blocked those... ugh. and now more driveshaft issues
