The jeep has a 318 engine. At times driving down the road the jeep acts like I let off the gas if I push the pedal further it picks up. Even at idle it runs ruff at times. No code when scanned. I have notice black soot on the ground at the exhaust sometimes. Could it be the tps going bad or what could cause this.
Thanks for your help. I will donate if you can help. And use your services because I own a auto repair shop. Getting into engine sensor repair. I fix auto AC for a living.
