2004 V8 bought it with 79000 three years ago. Ok, so at 80000 I replaced all the coils and boots. Now at 165000 it appears to need it again, missing like crazy especially on acceleration. Oil changes, tune ups and premium fuel religiously. No smoke or leaks, just did cooling system, but I drive this car 100 miles every day round trip. I drive it between 80 and 110, (I am a cop so...) eventually she is going to give out. Would you guys put in an engine or dump her? If an engine replacement is desired what are we talking here, cost, availability etc. Thanks
