misfire/bogging down?

Just recently had a clutch job done on my mach 1 and when i got the car back i noticed the engine would shake and rumble the hood of the car at 1000 rpms. If it dropped below 1k rpms it would run fine and likewise for north of 1k. I didn't think much of it cause the car ran fine for about a week. But today when i started it up the engine continued to run rough and the idle was rough as well as it making deep popping noises in the exhaust. And now when i give it close to WOT im a low gear the engine shakes and boggs down considerably and makes the same deep sounding popping noises. Didnt have any of these problems before the clutch job so idk if its related or not. Can anybody help me out please, sorry for such a long post

Ive had a service engine soon light on with a p1151 code (running lean) for couple months now and haven't noticed it till now. When i accelerate its very jerky and you can hear a popping noise from the exhaust like when tractional controll comes on when you lose traction but all the time.

P1151 is leaning out due to a rich condition. Sound to me like you are running really rich. I would check your plugs maybe one of them fouled out start there then look elsewhere but it may be either a plug or a coil. Also double check your codes to see if any others are popping up that may help you trace it down.

Ya replaced the spark plugs and coil pack and fixed the missfire, but I still have a o2 sensor problem saying I'm running lean after they replaced the sensor so it's frustrating
