buying naija used car ..even though cheap..in the long run..is more expensive!!!

Is the Check Engine Light on?

Try to change d oil pump in the gear,and c wht happen

@JUO and Earthrealm
I now know better. The owner did not disclose 70% of faults. I have spent so much and still far away from having a smooth drve.

@Costee
The check engine light is deffinitely ON

The vehicle is in Lagos now: dont want to risk driving it to abuja as after the return drive to Asaba and Warri more faults have arisen.
Pls can i have contacts to genuine Toyota parts dealer in Lagos?

I serviced the car before the above trip of about 1,317Km.

The new brake pads finished before Shaganmu. had to drive slow to Lagos.
The caliper springs in the rear wheel are broken.

If i can solve the initial problem of loosing power to as low as 700rpm and while you are pressing the gas pedal after some seconds it suddenly revs up to 4500rpm plus and down again before it picks up and starts moving after reving it for a long time.

Advice please?

Also observed leaking oil though small around the front gasket area. the mechanic assured i should not worry. your take please?

JUO: that was why the previous owner sold it. keep trying God will see you through. have you tried changing the coil?

Most people just sell lemons. the A/C he said only needed gas ended up changing the whole line.

What does the coil do? if bad where do i get genuine toyota siena replacement parts?

And you decide to ignore it? Scan the car and proceed from there. In so doing you'll have an idea of the electrical problems bugging the car.

@Costee - No i did not ignore it
After changing the fuel pump with a brand new one. problem persisted. Further replaced with a toks. check engine light went off for some hours and came back on again till date.

I am willing to rescan the vehicle if i can find one close to Festac Link bridge in Lagos.

Does that mean you had scanned it before? Do you remember the codes pulled? Since the light has resurfaced, I'd advise you obtain a scanner--very available (affordable?) these days. Then you'd begin to have greater control over what happens to your car. Pls scan before throwing more parts on the car.

if possible Cost aand Contact? Makes sense to me.

Contact Nissparts 08022228273

@Costee
Thx for the contact. I will call Nissparts. Cheers

NB: I will post progress on the vehicle.

Changed the two rear shock absorbers(N5000 for the pair) yesterday and sealed the top cylinder and manifold with a glue hopefully as indicated on the pack.

This morning i have decided to drive the vehicle through Lagos traffic and see if the leak persists also feel how the shock absorber performs.

Yes, keep us posted. Good luck.

Finally contacted Nissparts and will take the vehicle to him for scanning. Will post codes and suggested repairs for review here prior to implementation
