    Any brand names or anything I should look for for a cleaner? If I go into a AutoZone and ask for a MAF safe cleaner will they know or look at me dumbfounded?

    I know this is an old thread, however I am starting to notice some rough idle when I first start in the morning. As soon as the engine warms up, she smoothes out and she's fine for the rest of the day. I cleaned the CAI, replaced the MAF sensor and put two new 02 sensors. I am now thinking it may be the IAC. Before I buy more parts, I am curious what does everyone use to clean the IAC? I am thinking the CRC Throttle Body & Air-Intake Cleaner should work.

    Does anyone have any other suggestions or ideas? Thank you in advance.

    Someone mentioned you can change the fuel pump without dropping the tank. How?? My blue marauder stutters BAD when 3/4 throttle in any sort of TURN left or right. As you turn it stutters and then goes. Fuel pump?
