victoreyefia:


well noted. thank you. but do I need to worry about the radiator ?

double3:

Well u should not be so worried as long as u revert to coolant as soon as u can. Just drain the water from ur system (radiator and engine)and refill with recommended coolant and ur good to go.(Also don't forget to bleed the system ).

diportivo:



possible top gasket issues

GAZZUZZ:


My professional opinion is you have sticking valves. Most likely a sludge problem.

You should confirm with a cylinder compression test across all 4 cylinders.

i want to buy nigeria used toyota highlander 2004 or 2005 what do you think about that sir ? was it good

ozoneymcm:

I've been here long enough to know what Gazzuz will tell you

GAZZUZZ:


This one I have seen ladipo in your name, kindly post the vin of the car

Nostradamu:
Good day my fellow Nairalanders.

First off, thank you Gazzuzz for opening this cerebral vehicle troubleshooting thread. My respect also goes out to all other intelligent (and sometimes cocky, ) contributors that I've met along the journey of reading this thread from page 1 to 304.

So, all car wizards in the house, especially Toyota, abeg make una help a brother out. The thing is, my RPM is really giving me cause for concern. The idle is low, by any petrol car standard, yet it does not vibrate or stall. No, nothing like that. It's an old lady, quite old. But we've been lucky by cherry picking the type of Kazeems that have worked on it in the past.

Long and short of my epistle: Toyota technician referral needed. I have been driving around Lagos with RPM as low as 400 even with AC sef, car no dey vibrate. It bothers me more when the only code on it when it was scanned is an Evap: PO 446. People of god, abeg how do I go about this code and resolving it. This car no dey worry, but I know say na old age dey do am. Epp me, if anyone knows a reliable Toyota specialist in Lagos. On a scale of Kazeem to Gazzuzz, I'd prefer the person to be in the Gazzuzz range, biko. Na old car I get, I no kee persin .



See few details of car below and pictures.

Toyota Solara, XLE, 1999; V6-3.0L Engine. Auto Tranny. Shipped in from the US about 10-11 years ago.

-Car briefly hesitates indiscriminately some times when driving, then it smooths out. This started like 4 months ago.
-History of DTCs: 41 & 42 ABS (resolved) Evap PO 446 (on and off), current code. No other ones that me I know of sha.
-Recurring low idle RPM for about a year now; since issue started, NEVER gone beyond 500. Most times it's 400.
-More on the RPM: it idles between 100 & 200 MOST mornings when cold; but observed it idles around 600-700 in the afternoons ie usually when the temperature is higher. I know this may sound crazy, but that has been my observation. Don't know what to do again o.
-It gets crazier: I believe it should vibrate excessively at such low RPMS, but it doesn't, even with my AC.
-It speeds up pretty good for a 1999 vehicle: I seemingly catch up with much newer cars on the highway without much effort from my engine
-No history of overheating that I know of, but seems coolant in reservoir overflows at times as I observe precipitation on the plastic. I don't know why.
-Fuel consumption: Mm, Tank is 70L. At 145 naira, it cost me 10,150. Usually top it up with 5k after two weeks of driving (say home to my office, about 11.2km to & fro per day) because needle would be half way on the fuel gauge by then.
-Changed the PCV recently; although the old one looks physically different (Don't know if that matters sha) from the new one, but if fitted in nicely.



Thanks you for your contributions, I will take eet in good faith . By the way, big ups to: Radautoworks, Kingreignn, smartchoiice, dru23, nurey, diportivo, thebigkendo, autoelectng, weyreypey and all other gurus in this space. God bless una for the free knowledge wey una dey share here. Abeg, make una epp my matta.

Oga boss, Gazzuzz, tuale. As for you, I will personally see how we can push this your project a notch further into the realm of a reality show, walai. All cost on me. But make I go make money first . BIG UPS!!!

nurey:


have you confirmed the rpm reading using a scan tool? Your rpm needle could be faulty.

use a scan tool to read the rpm when can is working to confirm where the error is coming from

Nostradamu:


Oh, wow. So, just the RPM needle can be faulty? Thanks for this heads up. I have not scanned the car personally before, usually take it to workshops. I will explain what you just advised when I take it to a workshop. Two questions, nurey:

(A) If we establish that the needle is faulty, does that mean I'm getting an entire new display (or what''s that section called sef)?

(B) What about the intermittent hesitation and the PO 446 Evap code nko?

Thanks for your time, nurey.

nurey:


A. you will need a new instrument cluster or the rewire would fix the needle if it is not a board panel problem .

B. intermittent hesitation needs a physical diagnosis for that, physical inspection then solution to your problem

B2. That code for solara V6 is solved by changing the charcoal cannister located behind the fuel tank under the vehicle. Either over filling the fuel tank has destroyed the cannister or you have a leak around there.

read up on the link to point the technician on what to check first

Nostradamu:



B2 seems scary sha, but anything for my golden oldie. Okay, I'll do some readings on that link. Thanks, nurey. I'll keep you posted. Appreciate your time as always.

Nostradamu:
More pictures. Oga Gazzuzz, abeg no vex for all these media wey I dey take flood una TL o. Biko.

GAZZUZZ:

nurey:


don't change charcoal.cannister check it first and the other evap components to figure out which one is bad, the link has detailed pix of what to check which you can first do yourself to eliminate broken wire and hole in pipe.

replete:
Hi gazzuz, kindly help I just got a 2011 Camry the recommended oil is 0w20 please advise me on this and the interval of oil change. Thanks

GAZZUZZ:


Vehicle has an oil life counter . Just reset after oil change. Vehicle will remind you when it is due .

replete:

Thanks for your response sir, what I really want to know is if to stick to the recommended oil or just switch to mobil 20w50 like I did to my previous cars 03 Camry and 07 corolla. Thanks

Macmilla:

OK boss.
I don't have any misfire codes.
I don't have the equipment to check for fuel pressure, so I will swap out the fuel pump for a new one.
As mentioned, the exhaust system was worked on. Some Lagos boys decided to replace the bank 1 cat with iron wire, which was pushed down by the engine to block the 3rd cat. This resulted in a very loud leak as the air had to find a way out. All this was fixed and a new cat installed in bank 1. Bank 2 still has an empty pot (no cat). But the whole thing still sounds like there's a leak on cold start. Visible steam comes out of the tailpipe on cold mornings. So I'm pretty sure there's no restrictions.
