Recently had a few touch ups done on my '83 280ZX ( non turbo ), and when i picked the car up...it ( for the first time ever ) spluttered a bit ...and ran a little lumpy ...though i think it's smotthed out..after a back fire !
What the hell could that be ??? like...dust int the engine or something...injectors ???? I th had only been in the panel shop for about 3 days..!
Cheers,
