hay peps basicaly my gls has a nice problem with it...
you can be driving along perfectly fine and go to pull away from a junction or something and the bugger bogs down lke noones buisness.. takes about 3 seconds to go from 1k to 3k where it will acelerate but it still feels like something is holding it back..as you can imagin this is quite dangerous if your trying to pull out quickly. also happens on the motorway where the car will not pull more than 80mph
then 5 minuits down the road you can be pulling out of annother junction and the car will spin up and actually go realy well, or down the motorway it will feel like someones kicked it in the arse and it will whip round to 120mph
any ideas?
cars modifications
de-restricted airbox with standard filter
janspeed center and rear s/s
hoffman sport 200cpi cat (have tryed with standard cat and the same)
Astra GSi blades with 195/50/15
i have changed
coolant temprature sensor
air temp sensor
new cat
lambda sensor
any help would be great thanks

mine has a similar problem it struggles sometimes. my advice to you would be to give it a good service flush your engine out, change gearbox oil, filters etc.. this should sort it! i need to do it do mine!

nope engine light doesnt come on, does if you give it death tho... might try a coild pack but it dosnt feel like it missfiring. even tho when you do give it any stick it fels like it gets a missfire ner the top of the rev range.
oh and chris_gilly i gave it a full service plugs oil filters including fuel.. and i gave it a gear oil change when i bought the car as it was crunching into gears but fixed that with a good oil change..

X14XE has no air flow meter though, I think I have a good coil pack in the garage if you are interested, will have a look in the morning

I got 2 good spare coilpacks here if needed. Could be a number of things though but if its that intermittent it suggests an electrical fault

Had to replace the oil pump gasket about 10 month ago so changed cam belt and all the rest then... Checked bottom pulley then because i'd heard that they go there and it was fine..

I had a similar problem, and it was the map sensor plug was split and loose. So it kept giving intermittent misfires

My mates Vectra 1.8 was doing the same thing. Gave it a service and all was good for a while. Then the same problem started up again. He never fixed it, just had the car off the road. Then come MOT time the CO was a mile out.
It turns out it was the 90degree bends on the vacume pipes as they were old and had perished. Changed them and it's been good ever since.

Check the condition of all your vacuum pipes then. My mates vacuum Vectra is a 98 R reg so they are all 10 years old.
