I am an inch away from getting rid of this car! Nothing but problems since i bought it. Most recent one now is a no fire situation on cylinders 1,7,8. Last weekend I replaced the intake and carb on my 289 and everything ran great the car had more and power then it ever has with the timing set at 10 deg advance. Fast fwd acouple day. Car starts to mis at low rpm and at times doesnt start just cranks. Replaced coil everything runs well. Next day engine starts running rough while idling and low rpm and back fires through the carb. Ive replaced the cap,rotor,wires,plugs and coil. Reset the distributor at TDC and set advance at 10deg. Still runs like crap. Started this morning really rough idle Went to check timing and got nothing out of my light. Started pulling plug wires off while running and 1,7,8 dont change anything when pulled. Help!!!!
