just drove my mum's kenari, yr 2002 recently when she came to KL for holiday. it is a stock car.

i found the engine is sluggish and very high FC compare to my fren's kenari 2005. it is using single wired O2 sensor compare 2005 dual wired O2 sensor;

i have done the following this month;
1. replaced all engine mounting original from P2
2. throttle body cleaning by P2
3. using M1 5w-30 full syn oil as usual
4. 4pcs 14" new tyre
5. 4pcs absorber changed
6. full grounding installed
7. ATF flush and changed
8. stock air filter also replace. usually i replace it at 10k per OCI.

high FC, RM50 (current price), i manage to clock 180km max before refill and the engine is sluggish. my fren kenari which i drove last month for 1 week, have better response and FC is not bad. at least my same driving style and route is same. RM50 i can easily get 250KM.

thus, now im considering to change the petrol pump but i notice not many kenari owner change it. any advice for me?

thanks bro. yeah i also have done it since last month as following which i forget to include;

1. fuel system cleaning 3 bottle by prestone which i bought from ace hardware
2. techron done but seems no improvement - 2 full tanks
3. now testing shell 97 v power, 3rd tanks also seems no improvement but im getting slight better response only but engine still sluggish as it seems reluctant to rev.

hmm....done as well for spark plug, tried denso normal spark plug and now using ori P2 spark plug as well.

i do read up someone posted regard someone change fuel filter for his sentra here and found good improvement. then since my mum car with me now, im planning to change it but after Google for sometimes, i cannot find any information on the changing this fuel pump. when i asked P2 during my service with them, they said i can try to change it as the fuel filter is attached with the fuel pump. suspect maybe debris is clogging the petrol flow that contributed to my poor FC and power. however, they said fuel pump for kenari / kelisa, either yes / no answer. so im kinda risk to change it as well with no improvement as told. i asked my mechanic also said he never change kenari fuel pump before as well.

scratching head now

Ya, I'll send it check soon. Maybe I'll try to change the extractor as well to see any result or not.
