2.2 16v throttle problem
« on: 09 May 2013, 06:58:05 »
morning all,
im hoping i can pick the brains of the forum....

i have just bought a omega saloon 2.2 16v w reg, generally a good car, however there seems to be something amiss with the response from the throttle..
i noticed it after signing the paper work and completing the deal..yesterday.
the car goes into gear fine and will pull away under its own steam, but when you push the excelerator theres no real response i could have my foot planted to the floor with little response..
once on the motorway and at constant speed it seems ok..but no kickdown..
but driving arround town when i need to pull out of turnings, theres no response its a case of feathering the throttle to try and find a bit of speed....
ANY IDEAS..??????
i was first thinking i was too used to driving 2.5 v6 and above cars... :D
any help gratefully received
thanks
oh by the way im in surrey if anyone has a reader to hand.. ;)

Clean throttle body as first port of call

If sponge under scuttle is wet could be water in #4 pot. Check plugwells for oil, possible leaking camcover gasket
Ideally need to get the codes read.

Rear cylinder.. Numbered 1-4 front to back
Dirty/oil soaked plugs/coilpack certainly won`t help

Well. Cleaned throttle body..full of oil breather pipes all cleared. Changed the plugs. Slight improvement... >:( it feels like fuel is not getting through.... It hesitates when you press the throttle...? Could it be fuel blockage..? Still lumpy when cold.for about 30secs...then fine just no power..ticks over perfectly.. Anymore ideas...

Could be the cam sensor, you need to get the codes read.
