blaze Posted May 10, 2008 Share Posted May 10, 2008 98 OBW, fixed my engine stumble issue? It began about a month ago, every now and then while motoring along it would stumble. The only parts on this wagon that was not Subaru OEM were the spark plug wires. So I placed an order with my Subie dealer. In the time it took me to pick up the OEM wires I went ahead and swapped out the following parts I have spares for: Cam Sensor Throttle Position Sensor Fuel Filter (needed replacement anyway) Ignition Coil MAF O2 Sensors (replaced prior to stumble) Plus a couple more I probably forgot about? But did not fix the stumble. The old plug wires that were in there since I bought the car in Oct 97, were suppose to be recently installed by the previous owner? Today I installed the OEM Subaru wires, the quality seems much better they even sealed the joints between the wires and connectors. Took it for a 30 mile drive with NO STUMBLING The old wires were Belden Premium 7mm SAE Class F-MF. Quote Link to comment Share on other sites More sharing options...
wtdash Posted May 11, 2008 Share Posted May 11, 2008 Yet another post confirming the need to stick w/OEM wires. Why Subes are so picky, I do not know. Congrats on getting it fixed! Quote Link to comment Share on other sites More sharing options...

They are waste spark and aftermarket doesnt use the purest silicon for thier wires. They use cheaper stuff. nipper Quote Link to comment Share on other sites More sharing options...

blaze Posted May 13, 2008 Author Share Posted May 13, 2008 Update, After 3 days and 250 miles, my Subie's stumble issue is gone Not only is it gone but it seems to run smoother than it was. Especially during acceleration and shifting. This is a great message board, a wealth of information. Thanks Also thanks Four-Fleet-Feet for the keyless installation manual, but no luck, it didn't help me with my OBW Big thanks for taking the time and postage to try and help me :headbang: Quote Link to comment Share on other sites More sharing options...
