Went on my 400 mile trip and logged about 30mpg. Car ran fine except for some hesitation when I mashed the throttle down. Cruising down the hiway at 80mph, no problem! Today was busy cleaning the injector connectors (electrical), fuel filter, and installed the new O2 sensor. Should have seen the junk that flowed out of the filter, no wonder the filter was plugged. The SG36 universal O2 sensor seems to be working fine. I would recommend one of these. The last two items that need to address is cleaning the MAF sensor with cleaner and change the oil and filter. I will keep posting on any future developments, Steven.
