a dirty oneto causeidle and hesitation problems

A dirty carburetorcan causerough idle , hesitation and loss of power

its opening at idlewill ... causea low / rough idle and stalling

air leaks thru the carbswill causehigh idle and rough running

A leakcould causerough idle and excessive blow

depositscauserough idle and stalling Available

the Dash clustercould causerough shifting and high idle

The lack of airwill causerough and low idle

by engine deposits(passive) caused byhesitation , stalling and rough idling

the timing being off(passive) can often be caused byRough idle and hard starting

A dirty idle air control ( IAC ) valve in the throttle bodycan causestalling and rough idle

low timingwill causea low idle and rough idle

A / Ccauseshard starting and rough idle

A bad sensor or faultcan causemisfires and rough idle

to come offcausingrough idle , stalling and hesitation

depositscan causerough idle , knocking and stalling

However , when these electronics fail inside the throttle body , latency and tolerances increase in operationcausinghesitation , surging , and rough idle

faulty egr valve could be stuck partially openwill causerough idle and stalling

A low fuel level in the carburetorwill causerough idling , stalling , and hesitation

Carbon buildup on the throttle bodycan causerough idle and hesitation

a vacuum leakleadsto rough idle and hesitation

Watercan causerough idling and hard starting

Carbon buildup behind the bladecan causerough idle and stall

a lean mixture from the vacuum leakcausingrough idle and stalling

The IACwill causerough idle and stall

a double rich mixturecan resultin a rough idle and hesitation

just a little vacuum leakcould causerough idle and stalling

the EGR systemcausestalling and rough idle

Carbon buildupcan causerough idle and hesitation

but I thinkcould causehesitation and a rough idle

Engine ECUcan causerough idle and stalling too
