Today, I woke up and decide i'd tune up the Vibe Gt a bit.lately it has been running a bit rough while idling, And it has been 11k miles since the last oil change.I was told the car needs Denso Iridium IK20 @ $12.99 each. ouch!Those and an oil filter cost me $60.00, Then Mobile 1 extended $27.50 @ Wally World. that's some serious cash.After the plugs were installed, I went for a test drive man what a difference they made. I did find that 3 of the 4 plugs had been shorting out at the insulator and the boot, and 2 of them showed really heavy signs of it.I figure who ever installed them must have been touch the insulator while installing them. I would hope the factory does'nt touch them while building the Engines.

I have been thinking about replacing my plugs for a while. How many miles were on your car? It sounds like it made a big difference. Do you know if there are any symptoms or signs that I should look for that would tell me if I need to replace the plugs?

I think that those particular plugs feel better that stock regardless of mileage. At least on the GT.

Alright, thanks. I'm going to look into replacing those soon.

Mine was idling a little rough, That why I did it.Now it idles very smooth.

What mileage were you at when you replaced them? How was it, the last time I did plugs was in a '97 F-150. It was a nightmare- might as well of been a van.

the plugs are or should be very easy to get to, they are right under neath your engine cover
