had this on my other motor too, except it had ablown head gasket...

when i gas it fully, it doesnt give me full power. it like pops, and rumbles. iknow somebodys gotta have the same problem. maybe my map code and code 17, which is the speed sensor. i got a 90 da btw

 

Fixing the CEL is a good start then check
Fuel filter, cap, rotor, timing, spark plugs/wires

 

do a block test, if you dont know what that is take it to a shop it shouldnt be expensive.

 

You are most likely not getting enough spark.

Change your wires and plugs.

 

cant be my block. gonna check my wires. thanks guys.
