1996 tacoma 2.7 runs rough

i picked up 1996 tacoma 4x4 ext cab runs rough code 0340 put in new distributor,maf hardly starts misfires took off air box system sprayed choke cleaner thru system got it running and idling put together still running till i plug in maf kills engine any help similiar problems fixed?

 

might need a new maf sensor

 

put new maf in same problem

 

Might just be a bad spark plug wire...Might be running on 5 cylinders due to this. CHeck all your wires to make sure they are in all the way!

 

2.7 is a 4 cyl. The truck wouldn't cut off when the MAF was plugged in if it was a bad wire. It would mis like crazy
