Car Trouble

[scamb3]

Hi guys a wee bit of help needed. Everytime when i accelerate the car will reach about 5k rpm and then all of a sudden it loses all power. After a couple of seconds the power comes back. Any ideas to what the poblem might be?

cheers

Do you have a boost gauge on the car? If so what boost are you hitting when it happens?

Na i dont have a boost gauge in the car, so not sure what boost im hitting.

Sounds like boost/fuel cut but you'll need to see what boost you're making to find out. Borrow one for ten mins,

What he says or if it's stuttering could be coilpacks.

MAF unit.

MAF unit.

That was my guess but I know NOTHING, so it's not that

Does boost-cut not feel like the car is hitting a wall rather than just a power loss?

The car does feel like it is hitting a brick wall. Took it for a drive today and it was running fine, so not got a clue whats gong on.

I'm just down the road in Forfar and have just taken a set of gauges inc. a boost gauge of my old classic so if you need a wee shot gives a shout.

What year is your car? maybe able to let you try my MAF if its the same, mines is a MY99.

I have experienced boost-cut as the car was over-boosting due to a uprated turbo with no remap! I had it installed and was waiitng to get the map done and I got a little carried away and put the boot down. Felt like a hit the wall and the CEL came on.

It could be the maf sensor but typically that presents itself as more of a misfire. A total loss power sound more like boost cut to me.

Get the boost level checked and if in doubt do an ecu reset and see if it throws a cel up to make sure.

Check the usual problems,

1. MAF

2. Coilpacks

3. Boost hoses

4. Boost solenoid

5. Fuel cut

6. Ecu limp mode

7. Sparkplugs

8. Fuel pump / filter

My guess is MAF, I had the same thing with my V3 Classic, was an intermittent fault problems was it usually reared its head usually when i was just about to nip out past someone and dropped a gear! doh!

av got a similar prob on my02, its over boostin @1.5bar. but i think its cos of the induction and sports cat. so the service is next week then remap asap after

Jeez man! Can't belive you are driving your car into 1.5 boost-land with induction and sports cat fitted without being mapped! I'd be inclinded to drive off-boost until it was mapped.
