So awhile ago i bought myself a pair of obx headers on eBay. Put them on and first drive felt like ****.. all poppy and gutless.. checked my codes and it wasn't throwing any... i had some old pacesetter headers on before and it ran perfect.. so it just seems to me that the obx's might be the problem... but it looks to be more of an ignition problem.. the car runs fine if you drive it lightly but any extra gas and it starts popping. Sometimes violently..

Anyone out there thats heard of problems like this i could really use some info!
thanks!

Anyone at all??

 

Sounds Ignition related like you said. Doubt headers would cause it.

 

All the plug wires on all the way? Do you hear an exaust leak on the flange or see any carbon starting to build up between the head and header flange?

 

sounds to me like what happened when i cracked a spark plug installing some headers (... should have removed them I know)
