just got a complete tune up last month. changed the plugs and everything. I am getting a PO305 code and the engine has a blowback problem. why would it be doing that.?

you are missfiring on cylinder 5. you should check the spark plug and wire to that cylinder, they may have been installed wrong or the plug may have the wrong gap.

P0305 is a number 5 cylinder misfire code-there are 3 things required for a cylinder to fire(in the most basic terms)
Spark-Fuel-Compression
Lose any 1 of the 3 and you'll get that code, and the engine will run sluggish.

It sounds like you have a problem with the number 5 cyclinder, or an exterior problem causing no' 5 to operate inefficiently. Possible causes could be no'5 piston worn, or rings damaged, or worn, (causing low compression), thus, misfiring, it may be that although you have new sparkplugs, the no'5 plug could be faulty although being new, also, check HT lead to 5,and distributer cap for a broken or worn terminal, (Internal), check also fuel feed to that piston, could be "flooded" if plug not working correctly, or fuel starvation on no'5 if feed is dirty, /, blocked, etc. At worst, you may have burned/broken or unseated vale/s, at no'5. sorry i can't suggest anything more, but thats probably enough prob's to check for now Eh!, i sincerely hope this helps, good luck.

No indication as to what engine ? A blow back can cause the misfire. You need a compression check to see what is causing the blow back. If your "mekanik" can't diagnose the problem you better git and find one that can. NEVER change any part till you know the problem

if everything is turning off you might have an electrical problem such as a distributor module heating up a coil heating up or a problem with computer. on the other hand you need to eliminate the possibility of a fuel problem. check your filter or if it not been replaced in some time it might need one any way so replace it and have a mechanic run a fuel pressure check on it.
