Well ill start off by saying im 18 and i own an 02 BMW 330ci Vert for a year now and recently bought an auto 88 Iroc-Z with a 5.7 with 81k miles, i spend most of my time on E46Fanatics but i recently noticed a problem in the Iroc, once in a while it will idle pretty rough to the point where its shut off once , this is my first american car so im not too familiar with what normal is in these cars, any ideas?

In chronological order

clean your sensors

Sea Foam the engine

replace your O2 sensor

replace plugs and wires



remove the front bra------oops got carried away

 

just ordered 02 sensor and sea foam
as for the plugs and wires i changed those the second day i had the car

i feel the same way about the bra.. i removed it once already but it looks like crap since the paint is all faded
