pothole bill

that sounds like the problem!! I will have to think of a way to confuse the ecu so it looks like there is a speed sensor.

the loom has been chopped up , no speed sensors on this , the only things connected to the ecu are air flow meter,o2 senser,all the sensors attatched to the engine itself and thats it.

Over in uk subaru also offered the 2 ltr engine as well as the 2.2 . it has the stock ecu and the loom has been modified by a proffessional (just the wires to make engine run.... air con,power stering has all been cut out). It was out of an automatic but i dont think that would make a differance. Strange thing is it will run great for first couple of minuites then once it gets hot it will not go past 4500 rpm . could it be water temp senser?

no cats on it, the exhaust is a one off custom because its in a vw camper van.

Help needed. Engine is a 2ltr but been transplanted into a vw, it runs sweet for first minuite but after that it will not go over 4500 rpm, its like it is hitting a rev limmiter. I have changed air flow meter and o2 sencer but with no luck. I have seen other threads on here with same problem, is this a common fault? Any help appreciated.
