Hi my car starts fine but i work like on 3 cylinder no. 2.3 and 4. I don't know why but it mis cylinder no. 1 i check the sparplug, the sparkplug wire and the injector on that cylinder but they seems like good what else can be the problem??what else can i check to see why it mis cylinder no. 1

 

pull the plug out and check for spark with the plug on the wire again but out of the head. if you got spark, then its another issue. to keep the engine from starting pull off the other 3 plug wires. if you get spark on plug number one your injector could be bad or you have other issues. check the compression too. if you have a compression leak real bad in cyl.-1 it may not fir even with spark. try than and hit us up if that dont work
