I'm not good with this kinda stuff , I have just put in a msd distributor, new plugs and wires, also quick trip long tube headers and the y-pipe.

The car runs fine but there is a flat spot in the 0-2000 rpm range then it runs fine, any ideas as 2 what I did or could do 2 fix it?

 

check fuel pressure and scann for trouble codes.

 

x2. are you throwing any codes??

 

Did it exhibit the same "flat spot" BEFORE you made all the changes you listed?

 

No it didn't have the flat spot untill i put the stuff on and im getting a code of the downpipe oxygen sensors I was told i didn't need.
