Hi Guys,
Having another problem with my e30. I did some digging and found another guy with the same problem but he did`nt get much feedback on that specific problem.
Diablo also with the same problem - Dated back to 2006
Problem is:
At about 5500rpm when I`m full on the throttle it will feel like the car is hitting the rev limiter, but if I back off the throttle and ease it through you can continue to redline. But as soon as you go full on the throttle the car will misfire/choke all the way to redline. It does this on every gear as soon as it gets to 5500rpm.
So far I have changed:
Crank Sensor
Idle Control Valve
Inspection 1 service - (Oil Filter, Spark Plugs, etc)
I thought it could be because the car does not have a o2 sensor, so the car was leaning out at high rev`s maybe
. When I was under the car there is a nut in the o2 sensor socket and its welded shut.
When I contacted the mechanic who did the engine swap for the previous owner he said that the engine and ECU on the car is from a UK spec 325i, therefore it does not need an o2 sensor because they did`nt come out with o2 sensors on the English e30`s. Any truth to that statement? Because I thought all Motronic 1.3. needed it run an o2 sensor and catalytic converter.
Any advice would be greatly appreciated.
Cheers,
Trish
