running like crap

[cookmaster30]

hey guys my 92 talon turbo is running like crap. the other day we put in a walbro fuel pump, 550 injectors, and a safcll. i just bought the car and the guy i bought it from forgot to give me the charging cable and the software for the logger so no i basically dont have one. i got it running half way decent but yesterday it started running like it was only running on 3 cylinders. so i replaced the plugs and wires. that seemed the general place to start according to all the posts on here, well still running like crap. i pulled the plug wires one by one and trust me they are all getting spark, ouch. but when i pull off the one on the plug all the way to the left there is no change to the way the engine runs. what could be my problem. please help.

thanks
barry

Run a compression test thats what happened to me when I burnt a valve. 0 compression or really crappy numbers means you most likely need a valve job.
