well today, i drove my car to a friends house and then we took about a 40min drive to another city. we stopped at a friends house and we only stayed for about 30mins. well....this is where it gets weird. i start my car , sounds fine and everything. i drive off and it wont rev past 3000 RPM !?!? i need to get this fixed fast if i can because unfortuately i have work to go to!!! crap!! can anyone help me out??? thanks in advance.

 

its about 80-85 degrees outside if that factors into anything

 

year, model???

 

I've had the same thing happen to me...LOL but it just went away!

 

its a 1986 gxl...and yeah like the above, it just went away after about 40 min

 

fuel filter clogged?

 

do you still have the OEM cats???

There is no limp mode on a S4, so that rules out anything but a clogged intake or exhaust, or major leak on the intake.

 

i would guess that because there is an increase in feul threw the feul filter that if there is a wall that it hits....its the secondaries not gettin any fuel thus adding a lean mixture......maybe???

i have a similar problem but is a hesitation after adding my rtek 1.7

 

check your secondary injector plugs.

 

Was the engine up to normal operating temp?
I notice if I get too aggressive with the throttle when the engine isn't totally warmed up, the secondaries just don't fire at all!
I feels like a hit an abrupt wall.
