Have owned car for 70,000 of it's 175,000 miles. It's been surprisingly trouble free. Changed plugs, wires, and oil two weeks ago and was running great (eliminates wire mix-up). Suddenly car is hard to start, rough running, and cannot get engine over 2500 RPM (even in neutral) without really working the throttle (softly). Low power. No codes (did get a P0500 after working on it but appears to be unrelated), No unusual smoke. Replaced: fuel filter, Air filter (very dirty), PCV valve. Checked spark, compression, PCV hose, Fuel pressure (35-40), MAF(cleaned), CAT covertor(dropped CAT off exhaust header). Still working on testing some of the other sensors one by one (TPS, knock.). After all this, it still runs really bad, pretty much undrivable. My question is this, I suspect the timing belt has slipped a tooth, is this possible and the compression to still be good? (All cylinders 180, unknown what reading was prior to engine trouble)
have the same problem?
