It does not seem to mis under initial load, eg my driveway is steepish and if pulls up it without any hesitation and feels really strong. the mis really shows itself when at cruise speed, any cruise speed. but less then what it was before I out the new cps in.
also it did run well initially after sitting, and at one stage was pulling just over 8 k's per litre. Everything it has been doing seems to vary. eg when the computer was reset the first few times it cleared right up and went like a train. Now that the mis has settled in, although now less with the new cps as mentioned above.
feels lumpy also, surgy.
maybe a faulty MAP?
or maybe its the main computer playing up.
