When you say you've done all checks do you mean you have done ECU error code check and nothing is logged?

Ok mate let us know what codes you get and how you get on.
In some cases a faulty maf can be repaired or cleaned so sort the problem

bigpetebrit

will do.

hi mate its the knock sensor and AF sensor+1 systerm what do that mean

32 will be your lambda sensor. 1st thing I would do is an ECU reset to make sure they aren't old codes that are stored,take the car for a drive and see if you get the CEL coming on again. If you get the knock sensor error again then I would change that 1st as I would of thought this could also be causing the lambda fault.

bigpetebrit

hi mate what is lambda andknock sensor

Have you done an ECU reset?
If you don't know what or where these 2 sensors are then you're best off taking the car to a mechanic to fix. Faulty knock sensor(located on block,under the intercooler) could cause big probems on the engine.
Lambda is in the exhaust downpipe.
Do some searching on here mate or just take it to a garage

bigpetebrit

your a star ......just got wrx there no lambda on down pipe

Is it a standard catted downpipe? Or does it have an aftermarket decat fitted?
Lambda should be in the top of the downpipe on a version 3/4 WRX

bigpetebrit

wear it fits on the down pipe its got a bolt in .it looks like a aftermarket one.no cat on car its been remapped by power enginering

Sounds like possibly the aftermarket downpipe has been fitted and lambda sensor has been left off. You will find the connecting block with nothing plugged into it. The car should be remapped when fitting a decat downpipe. Running with no lambda will cause problems as the ECU can't read afr's in closed loop. This will cause knock/detonation and could destroy your engine. The only/best way to remap a 1998 classic is with an ESL board or aftermarket ECU fitted.

Like I say,you are best taking the car to a Subaru specialist to be checked out. Richard Henry Motorsports in Bradford West Yorkshire come highly recommended and not to far from you.
