Did you change the distributor? Could have put it back in the wrong direction or forward too much on the timing notch or put too plug wires on the wrong post..... It definitely sounds like a timing issue and the back fire sounds like the plug is firing the cylinder on the intake stroke.... if you keep at it you will blow your muffler off or start a fire. Look up the firing sequence for your year and make of car to be sure
Back fire back to where, the intake or exhaust. intake backfire is a pop sound, not too loud, and is bad timing. exh backfire means, fuel plus air is in the exh. and explodes with a loud report , we call it muffler explosing to help with clear meaning.... in this latter example you have a bad running motor (rich as pig) a dead CAT and exhuast air leak all at the same time.
if you spray intake cleaner into the intake with the air snorkel off and it starts then i would say you have a fuel pump problem.the backfiring was probably caused by the motor all of a sudden going lean.you will have to check the fuel pressure with a gage it should be about 35lbs pressure to run the car.if the pump needs replacing change the fuel filter.
Back firing out of the intake is because the valves/cams are not set right. When you did the timing belt . did you set the crankshaft mark at top dead center of the compression stroke. If it's at the exhaust stroke this would cause backfiring and violent shaking.
Did a little research, sounds like the hold light is linked to the transmission, used when needing higher rpms like when towing up long steep hills. The back fire and bad smell could be two things, either insufficient fuel, or bad spark. The spark plugs and wires need to be checked, and also the fuel pressure and flow rate. Is it back firing from under the hood or behind the car?
dear friend-to me it sounds like you have a intermmitend spark,it could be that your plug lead sparkplug or coil pack can be at fault,fuel gets injected into the cylinder but only ignites every second time around meaning two injections one spark in an overfueled cylinder,please be careful the back fire will damage the airflow sensor
