would love to say what mph but speed sensor playing up

I'd say that wouldn't be helping but check for error codes on the ECU.

iv got the same problem, the car would feel like iv just hit a brick wall and it sounded like the engine would stop then turn back on, i asked on the forum what they thought it was and nearly all of them said it was a boost leak

Wet air filter can cause this , if you have an aftermarket one fitted see if it,s damp if so take it off and leave it in your airing cupboard overnight .

Had the same happen to mine :headvswal

Your speed sensor failing will cause both your speedo to misfunction and your steering to go excessivly light/heavy only. I have added some possible scenarios below.

 

scenario 1

If your car violently shakes right before slowing down "like you have hit something" then my guess is that your CAS "crank angle sensor" connector is corroded or damage. Start the engine and wiggle the harness feeding the CAS, do you notice any change in the engine revs?. The CAS's them selves are very reliable "made by mitibishi" so don’t worry too much about replacing it. If your connector is corroded then do your best to clean it as you cannot buy them separately.

 

scenario 2

If when it slows down can you still rev it in neutral gear ok?. See if it will rev passed 3k without spluttering.If it can go to next step If it cannot then check your MAF "mass air flow" connector for damage/corrosion. If you have checked for corrosion, re-seated it and it still wont rev passed 3k then disconnect the connector from the MAF its-self and see if the engine stalls. If not then your MAF is at fault. If it does then try next step

 

scenario 3

sudden loss of power can commonly be caused by cracked/corroded Coil pack

and injector connectors. Start engine and with the aid of an extension of some sort "thin screwdriver, piece of wood anything which will fit", push down/wiggle each of the 6 injector and 6 coil pack connectors in turn, note for engine rev change. If you have find a faulty one then un-plug and try to clean it, if its too far gone "most are" then you can purchase both of these type of connectors relatively easy now days. It is common for the actual injector tops to corrode “green colour” borrow your misuses nail file “sand paper type not metal” and gently rub up and down on each injector top until you can see clean metal.

 

If you have checked all the above and you still cannot pin point the fault then it is highly likely you still have an electrical fault. Check battery terminals are tight and your battery to body earth cable is ok. Also check the positive cable from the battery to the alternator.

 

Have someone run a full Consult diagnostic and display any stored error codes. Put any codes on here as someone will translate it for you.
