HI All Thanks in advance
1990 GMC Suburban Vehicle has been running smooth no problems except it needs new exhaust from muffler out. I'm wondering if this has to do with my current problem. Started the vehicle yesterday and it ran rough, started down the road and it felt like it wasn't running on all cylinders. Very noticeable expecially when first starting out. I turned around and parked it after a 1/4 mile. Where should I start? Thankyou Ross- posted
