Losing RPMs

99 Honda Civic Si. (1.6 DOHC VTEC)

Ok so heres the thing. When i drive occasionally for over 10 minutes my
car will start lossing rpms. For example: I will drive the car okay for
10 minutes than all of a sudden i will be in 5th gear and when i let
off the game the rpms will almost instantly drop down and my car will
start jolting.I am getting a constant check engine light. When i shift
my car jolts also dure to the rpms instantly droppping. I was told it
could be a nox/knock sensor (not sure how its spelled/pronounced)

 

have you had the ignition switch recall work done on this vehicle?

 

im not sure i havnt had the car for too long

 

a dealer should be able to look it up on the central computer database.
replacement is free because it's a safety recall and symptoms are just
like you describe. if that's not it, get the diagnostic codes from the
onboard computer and report back. a lot of auto parts stores do this
for free.

 

the "check engine" light ought to be a clue;get the ECU trouble codes read
to see what is the problem there.

 

He -might- want to get the trouble codes read FIRST,then worry about the
ignition switch.

 

Thanks everyone. I will find out then post here thanks again.
