hello everyone. I am having some serious engine problems. I have a 2000lsv8 with 69k miles and for some reason in the past 3 months i have had to replace 6 engine coils. I dont know whats causing this but even after getting all the coils fixed i am still having problems. My car just doesnt seem to run like the car it was when i got it with around 63k miles. I step on the gas and there is a hesitation. I am driving on the highway and slow to about 40 then step on it again it bucks and jerks. Are there any reasons why this is happening. Please help.
