Since putting new engine in, and new ptu,

TT now ticks over perfect, adjusted idle and all is good. But.

When stationary under no load , engine revs lovley, but turbos dont go (i think) as boost gauge stays at 0.

Have cleaned every connector in engine bay and all are working, when driving it wont go over 3000rpm so i guess safe mode. Have replaced temp sensor and it works 100%

 

When i killed the last engine the drivers side of engine was were the leak was and i guess water got into exhaust pipe. Ive established that the cat was blocked so its now gone, the passengers side is great and when reving it has lots of pressure.

 

Problems are:

 

1. Have done ecu check shows 55, so all good, and reset it overnight but still wont go above 3000rpm. what can it be?

 

2. There is virtually no pressure from drivers side exhaust even with cat gone, is it possible that the water travelled down the pipe and whilst car sat still for 15 months, has rusted it up ( ie was removed on car trailer) so if there was water in it, it would have defo gone to rear box too.

 

Help ta

Not revving past 3250rpm is MAF plug. Check it is seated correctly, clean it if needed.

yup deffo maf

ECU should give an error for that and the rev limit should be 2400rpm.

Cheers folks, will give that a try. and see what happens

Have checked and cleaned connections to MAF, which looked clean no green stuff on. If i remove the connector with the engine on tick over, it stalls, replace it and it ticks over fine, it is securley in place. but still in safety mode when under load. is there a way of checking that the maf is shagged or not, or just give up and buy another one,

 

has anyone any ideas on the pressure from the drivers side exhaust, it is so close to being perfect i cant give up now.

sounds like a siezed tub to me bud or when it stood has some crettin crawled up the pipe and made a nest :D

To answer the other part of your post about turbo pressure when stationary.

 

You shouldn't get any turbo pressure above 0 psi when you are stationary, that's normal.
