I bought 3M Fuel System Tune-Up Kit from Amazon a while ago when they had it for around $20, and with $10 rebate the final cost was about $10-11 after tax.
I used it to fix the low idle in the 2006 Volvo V70 with 16x,xxx miles last weekend. Every few days the car had CEL with code P0204 or something like that.
Used the kit as instructed and it did raise the idle from around 500-550 RPM to 650-700 RPM, engine is running much smoother now at all RPM from idle to 4-5k. No more CEL since last Saturday.
Just checked the price on Amazon, it is $39.xx now. If it drops to around $20 and with $10 rebate I will buy few more kits.
