I recently purchased a used Sube Loyale with 70K miles for a song (speak, 800$). I'm currently doing all I can to get the engine up to speed (literally). I've already done the basics, plugs, wire, filters, etc. (fuel filter seemed to be original from 92!) and the engine is already sounding better, but there are some minor annoyances I don't know how to deal with:
- AC compressor is making an annoying swish-swish noise the minute the engine turns on. After an unrelated engine compartment wash the noise actually stopped for several minutes before coming back. Could this be a dry or misaligned belt?
- Check engine light is on and from what I can gather, the solenoid valve is at fault. (assuming a repeating 3 long blinks and 4 quick blinks means a code 34) Can I somehow clean and reinstall this or is there even a way I can disable the whole EGR circuit all together AND have it not affect the diagnostics readout?
- Are there any mufflers that I can use on my car that will allow better performance but NOT sound like my car has indigestion? Or can I just grab a Dynaflow (or whatever the name was) from Autozone?
- Any other tips for improving the overall performance of the car, save getting a larger engine? :-)
