Ok, here is the situation. I recently purchased an '00 maxima for a very good deal, has 200,000 KM no check engine light, clean inside and out, beautiful Glacier Pearl paint job...
Symptoms of the unknown problem are:
1) 8 KM / L (roughly 19 MPG) 2) 0-60MPH in 9 Secs. (Way below the average 7.5 secs. that I see others get) 3) Between 2500 and 3500 RPM I feel a drag when flooring it. (Like something is holding the car back)I recently got a highmileage oil change. Did a 4 step emissions cleaning (which includes seafoaming), did not help at all.
Is this a MAF issue?? I've been reading that airflow and dirty sensors are the culprit of most gas mileage and acceleration problems, but others with the same problem did not notice a change. I took a look at my MAF and it looked clean to me.
What else could I do to diagnose the problem? I would really appreciate any suggestions or advice.
Thanks!!!!!!!
