My friend the car backfires if its runing lean ( insufficient fuel ) or runing rich ( insufficient oxygen ) this mostly in carbourated cars would make incomplete compustion . in engine with fuel injuction there may be a leak in the intake valve that makes the fuel to burn in the exhaust pipe . so check for leak asap

I would suspect a burnt valve. An engine compression test will verify this.

Engine stutters or stalls after a complete stop upon engaging to go forward


You'll need to have someone scan the computer for the codes.
Most auto parts stores will scan for free in hopes of selling you some parts. Once you get the codes you can research them online or in this question.

Runs no power stalls out on the road when you give it gas it won't go just sputters and pops like it is backfiring,but it doesn't do this all the time.


Pull the distributor and check the drive gear on the bottom if there is any wear besides just being shiney replace it. you can replace the gear or the whole distributor. let me know we'll go from there
