Throttle hesitation from cold start-up
Mk5dub:
I would appreciate some advise on an irritating problem with my standard Mk5 GTI. (50,000 miles)
From a cold start I have a noticeable throttle hesitation. Literally one minute into a journey and the engine characteristics return to normal.
The car has been well maintained. I have replaced the D.V, PCV, & the Coils,
What's your thoughts please.
Danbear79:
I can't help unfortunately, but my gti does exactly the same. I dont accelerate hard until the car is up to temperature, but I would love to know why this happens. Changing to a Rev g didn't help, bit it definitely made my boost come back :signLOL:

Plugs? Possibly carbon buildup
GrayMK5GTI:
Don't all engines do this when "on choke"?
Engines don't work their best (and shouldn't be thrashed) until they're warm :happy2: the ECU is dumping fuel into the exhaust to heat up the cat and trying it's best to get up to operating temp. Wouldn't expect it to drive wonderfully as well. . .
My ed30 and my old GTI were unresponsive from stone cold
Pikey Motorsports:
Not sure if he means hessitation as in slight hickup/missfire
