...seems not to like it!?! I get a 'check eng light'. What's up with that? I've been getting it since I got the car a month or so ago...I just assumed it didn't like the way I was driving it around at higher RPMs...NOW it's starting to get annoying. It clears itself after a day or two or after a nice, easy drive around (still after a day or two). It stopped for a week or so after removing the air silencer and dropping in a K&N element. Car also has 3:73s, weld in Delta 40s, otherwise stock...with 108,000 miles on it...I assure you, it still runs perfectly! Anyone??? Thanks in advance kids!
