hey fellas im just writin to explain something that just went wrong with my car its a 2000 firebird v6 a4 and it only has 40,000 miles anyway i just noticed the car has been backfiring, hesitating, rough idle etc dont know wut it could be??? and i just stuck 93 octane gas in last week but i dont think that wouldve done that cause i always put 87 octane in. if anyone has any ideas of wut this could be please help thanks!

 

Bad Cat??

 

just replaced the cat a month ago but its weird, this problem came outa nowhere. it feels like the traction control is on and im spinning my tires like the engine just hesitates and the exhaust pops?the only thing i could think of is maybe a bad injector, or spark plug?

 

you might need new spark plug wires, they tend to go early in our cars due to heat.

My car has 53k and I've had the wires changed 2x now and I might need it again

 

ya im gonna get new wires this weekend thanks

 

do plugs as welll....


i also suggest reading the "great misfire mystery" thread at the top of this section...

 

id say plugs and wires..
