pls help:
I drive a lexus rx300, 2003 model. after driving for about an hour yesterday, i noticed some vibrations which later increased.
the check engine light which is usually on started blinking. all this happened for about 10 mins & stopped. the vibrations were not jerks but vibrations. i had done a scan about a year ago when i bought d car but d person who did it said there is nothing to worry about the permanent check engine light, that its our type of fuel in Nigeria. & i have been enjoying the car though the i percieve gas smell from the exhaust when i buy fuel in some particular stations. pls help with this vibration even though it has stopped.

kindly clarify, i noticed same school registrar for Covenant Uninversity and Babcock University on this platform. thks

Hi guyz,
I have read so much and hardly would I tune a radio station without my listening to peeps discussing this supermarket expo and how it has changed their fortunes.
is it real or a way to swindle unsuspecting Nigerians. if real, what are the prospects, the commission, challenges et al.
kindly share your experiences.

Hi Maestroz,
All you have heard is for real. I am in it and it has changed my life positively. It has also changed my mindset. All you have heard about it is true and i invite you to come on board.
You can call me on 09096974510 to get more information about it. Thanks
