Ok guess I'll have to buy one. Have another question. Do the fuel injector system start making a popping sound when it's going bad or is that the cat?

 

[retorq]

Pop like out the exhaust pop??

 

[97tahoess]

Yeah you can only hear it when u driving.

 

[97tahoess]

Ttt

 

[retorq]

Popping out the exhaust is unburnt fuel leaving the chamber, it's normally associated with a spark issue, as in one of the cylinders isn't firing properly.

 

[97tahoess]

Could this be the fuel injection system when at normal idle it's run fine there's no missing or popping it run perfect.

 

[retorq]

Not likely.

 

[97tahoess]

Any suggestion on this? I'll be sea foaming the engine next weekend.

Check the plugs and wires, cap and rotor for starters.
