R32 Engine Problem

[lows_13]

Last night i was driving home and all of the sudden when i put my foot down to rev up 3rd gear the engine started to shudder like it was about to run out of gas (the was half a tank of gas in the car). The problem continued for a little bit, i was able to drive home by keeping the rev's under 3000rpm. I rev'd out 2nd gear a few times on the way back home, and everything seemed fine.

Yesterday i took the atmo bov off and connected the standard plumback setup back on, so not sure whether that has anything to do with it.

Also on the odd occasion, when i'm driving i'll put my foot down on the gas and for a split second theres the slightest of hesitation before the engine starts to rev up. Almost like one plug is fouled up.

Any ideas of where to start?

Fuel pump?

[ToF]

Coilpacks?

Need to know more details.

The car seemed to rev up ok when out of gear, but when i put it into first it started to play up again.

Seems like the engine didn't want to be under load.

fuel filter?

[lows_13]

I reckon thats the first course of action, change the fuel filter.

Any recommendations after that?

[Benno31]

fuel filter then get your coilpacks tested while under load.

it could even be a bad earth somewhere.

best of luck

I have had this issue due to the stock BOV recirc hose being split. could be the problem

[lows_13]

The rubber hose or metal pipe?

I've only run into this problem now that i've put the standard BOV and

plumbing on the car.

What would happen if the standard BOV was to leaking under boost? (would it cause this problem)

qwhat's it like on boost vs off boost?

if its only bad on boost (like above 2500rpm), maybe the afm has a bad connection?

check computer fault code blinks, will be afm seen it plenty of times.

[lows_13]

Where is the light located for fault codes?

I'll try an ECU reset as well.

Sounds like fuel pump.

It wouldnt hurt to look at your coil packs etc.

Mate, I had similar problems.....the car would be fine during th drive and on the odd occassion, it would shudder and would not respond to the throttle. I've got a multi display screen in car and I can see when this happens, there is no fuel injection at all! Had it checked out and it appeared that the AFM sensor had fouled up due to oil mist build up from the K&N panel filter....at least that's what I've been told...had that cleaned up and problem seem to be gone.

[lows_13]

Same thing happen again when going for a drive, only occured once in the hour i was out. I've cleaned out my afm last month, i might give it a second clean.

[iandawsonwa]

had the same problem got a new fuel filter and fuel pump that worked for me

Did you only encounter the shuddering once ever now and then?

[iandawsonwa]

Yer it would come and go and then some times idle realy low to and sometimes run fine. I also thought it mite have been a miss but when i checked the plugs and coil packs thay all seemed fine. you should change your fuel filter every 60,000 any way

[lows_13]

I reckon i'll change the fuel filter, then fuel pump. Hopefully the problem

will be fixed after that, not sure what to do if those two options fail.

It could be a lot of things but my money is on the afm.

The pins are soldered to the circuit board.

These solder joints get broken by wriggling the plug to disconnect it.
