SOS Please help
#1
Is there anyone out there who could help me please. The problem I am experiencing with a 1995 Jap WRX is that it cuts out the acceleration between 4000 and 5000 rpm. If I suddenly want to take off it will quit accelerating at 3000rpm but if I gradually build the acceleration up slowly it will go to the 4000/5000 rpm and and give up acceleration. I also notice it is running without the turbo kicking in. When travelling at constant speed of roughly 60 / 80mph the accleration will shiver... I am confused... what could it be... Please help :-( For a fuller description of the problem please see the 'drivetrain' section in the technical heading forum of the scoobynet.

Don't know if you've solved this yet 'cos its gone from the 2-days view of Drivetrain. Sounds like the ECU has thrown a wobbly and gone into safe mode. It has happened to me several times. As long as the check engine isn't showing any fault codes, reset the ECU (do a search to find out how) or simply just disconnect the battery -ve terminal for a few minutes and reconnect. Fault show go by magic.

It could be a number of things causing it to revert to limp-home-mode.
Get it to a garage with a select monitor.

Had the same on my MY93 WRX, check the coil packs. Theyre made of a hard bakelite type material and are prone to cracking.
Remove them and pull the rubber end cap off. Inspect em very carefully and you may well find a hair line crack. I did, and with that coil pack replaced, it was fine. It was explained to me as the spark being blown out.......make of that what you will but certainly worth a DIY check.
The next step is the ECU but Id doubt its actually in reversionary mode as the check engine light shows this.
Good Luck
