Best Throttle Body Cleaner

Throttle body cleaner strips the carbon and gummy varnish that builds up on the throttle plate and its bore — the gunk that causes rough idle, stalling at stoplights, and that hesitation off the line on older cars. Pop the intake duct, spray it on a rag (not directly into a drive-by-wire throttle body), and wipe the plate and bore clean. Pair with a fresh air filter and, if symptoms persist, MAF sensor cleaner — they tackle different deposits in the same airstream.
