How do I fix throttle lag problems when accelerating my VE SV6?
Had the throttle body replaced today on my V6 Calais and it’s much more responsive now. Acceleration was dodgy and there was no engine light up but it would sorta jolt you around and the revs would surge and hesitate for no reason. And it made whining and grinding noises before starting and after turning the car off.
Thanks for the reply adc,
The lag creates the engine to rev out if put foot down too quickly when trying to overtake. There is about 15mm play in the pedal before I get power....
It wouldn't hurt to replace throttle body at 187k anyway and go from there. Was thinking about a throttle controller and then heard they put more strain on engine and stretch the timing chain. Stretch timing chains are known on VE anyway without something else adding to it.
It's great the throttle body has fixed your surging and grinding etc problems. That sounds full on especially when you don't know why that would be happening. I don't have any warning lights either.
Sprint booster....simple and effective. It just reduces the range of pedal parameters...eg 1 inch of pedal movement becomes 1 cm of pedal movement.
All the throttle controller does is quickens up throttle response, it does not put strain on the engine, no difference from a spring booster effectively
Tried cleaning your throttle body?
Cheers for the feedback guys,
Yeah, a mechanic told me it strains the engine, good to hear other opinions on throttle controllers.
Sprint boosters sounds great and ill checkout the throttle body
that would be my first thought too , to the OP the VE has a fly by wire throttle body , so don't manipulate from the engine, take off the intake piping to the throttle body and turn the ignition on but do not start car , have a mate push the throttle pedal to the floor and spray throttle body cleaner or similar into the open throttle plate give it wipe with a disposable cloth or if it's really gummed up use an old toothbrush , that might solve the problem .
My ve (v8) has the same fly by wire throttle body setup I clean my throttle body by pushing the butterfly open with my fingers and has never caused any problems although the best way is to take it right off the car especially if it’s really dirty
I have pushed the butterfly open on mine to clean it with no adverse affect and mine is an sv6 .
I cleaned the throttle body today, but found it quite quick and easy to unplug the harness, undo the four bolts and remove it fully. Complete clean in 15 minutes.
Thanks for the info Guys,
I'll check it out and it and clean to see if there s an improvement.
How old is your air filter? If that’s old and clogged up ur car will be gutless and laggy also
Air cleaner looks ok, going to change plugs and filters anyway with next service this week.
I haven't had the VE very long and not sure how it has been serviced even though the services have been dated in the logbook.
I have had 3 VE's now. And all of them have a slight second lag from when you press down on the pedal to when you actually move.
I installed a Revhigh Throttle controller to my first stock SV6 and no bullshit, you definitely feel a difference. Highest level spun the wheels so easy.
In-fact i actually started to love my sv6 alot more after installing it. It makes the car feel how it should have felt from factory.
When I upgraded to the r8 next, as much as I wanted to, I didnt have the balls to install it because it had already been heavily modified / tuned.
Thanks for the feedback Xplaya,
Yeah I looked into the RevHigh throttle controllers and saw the reviews on YouTube, easy to install and they do improve acceleration
