Help me please. I feels like the fuel isn't getting through, I thought it might be maff sensor but code check revealed nothing wrong anywhere?

Only happens down the revs once the revs are up its fine????

Anyone shed some light on this prob?

Cheers.

Is it misfiring?? Could be plugs.
Also try cleaning the maf sensor, idle control valve and boost solenoid with carb cleaner. Do an ecu reset and see what happens!!

Cheers m8, no its not backfiring I would clean the other parts if I new where they was m8

I know the maff sensors ok.

sounds like it might be a bent valve. Have you done a compression test on it ???

sounds like the coil packs are breaking down, this is a common fault on pre 96 cars.

timjohnson

Do you use octane booster, If not give it a go , i also had a similar problem with my93 ,put the booster in whew.

Nick200

I am running octane booster at the mo so it cant be that.

Its at scoobymania having spoilers and brakes fitted and I told them to find out what the problem is.

Lets see if they can fix the problem without it costing me a fortune.

Keep you posted.

P.s thanks for the advise I will pass it on.

I WOULD ADVISE ANYONE WITH A 93 WRX TO GET A 94-95 WRX 260 BHP ECU BEST MOVE I MADE. SMOOTHER 20 BHP MORE NO HESITATION OR FLAT SPOTS.MERVE FROM POWER ENGINEERING (ECUTEK NOW) GAVE ME THIS TIP 5YRS AGO(£150) IS ABOUT THE GOING RATE FOR ONE.

spiderbaby

how would you identify an ECU out of a 94-95 wrx. the code on my ecu is U8 what would the code on a 94-95 be?

muly

The code for the late 94 on will have a Z4 sticker on it, they are so much better
