add ko lang.. the real reason for this practice is for the oil to have sufficient time to spread sa engine.. warming up (heat) makes the oil thinner therefore allowing it to spread better. kasi when you rev it high right away friction in the engine will cause more wear and tear so iiksi buhay ng engine..

 

 

 

check your groundings. may maluwag lang dyan..

or you can have your car install an extra grounding kit, baka naman kasi nagkukulang na sa negative ang groundings mo...

Going higher octane is rarely a problem. It's when you go to lower octane that there could be a problem if your car requires high octane.

Normal ba ang 2500RPM to 3000RPM when driving at 80KPH?

[baloney0319]

Normal ba ang 2500RPM to 3000RPM when driving at 80KPH?

 

It depends, more information needed:

1. what car model and engine displacement

2. in what gear are you in

3. what road condition, sloped or downhill

I do have a 96 Sentra Series 3, I do have a problem where while driving, namamatay yung car, but fortunately I can start it again. But while driving, namamatay ulit, especially when I go neutral... I have a new battery and changed alternators. It happens when the aircon is ON and also at night when my headlights are also ON. But there are instances that it does not happen. May I ask what seems to be the problem?? Thanks a lot.

 

check mo din bro kung tama talaga yung amperes na kinarga sa sasakyan mo, i had mine before 65 amperes then nung nasira, 110 yung kinabit which is ok naman basta wag lang mababa sa 65 then after 2 years sira uli alternator ko then bumalik ako sa 65 kasi yun ang tamang amperes sa sasakyan, which is 65..

 

maybe yung kinabit sayo is mas mababa than the normal amperes that is required but it also helps that you check the wirings...

 

if you're near MINDANAO AVENUE, check mo yung SHELL after ng ST. JAMES, ok yung mechanics nila....

BREAKING -IN A NEW CAR

(from popular mechanic by Fritz Springman "Whip Those Horses" year 1965)

 

When "Breaking-In" a new car, it should neither be driven too fast nor babied.

High speed driving will result in scuffed pistons and rings, and scored cylinder

walls. On the other hand, consistently slow driving will not properly break-in

an engine.

 

Use the "Whip Technique" when breaking-in a new car:

ALTERNATING PERIODS OF SLOW DRIVING WITH FEW SECONDS OF FAST DRIVING.

 

Break-in a new car on a stretch of highway where traffic is light. Start at a

speed of 40 kph. Then using a half-throttle acceleration, the car is whipped up

to 55 kph, the throttle is released and the car allowed to drop back to 40 kph.

After a short run at 40 kph, the car is again whipped at 55 kph. This procedure

is repeated for the first 150 kilometers.

 

At the end of each 150 kilometers, the whip is stepped up as follows:

 

150 kilometers, whip up from 40 to 55 kph

300 kilometers, whip up from 50 to 65 kph

450 kilometers, whip up from 55 to 70 kph

600 kilometers, whip up from 65 to 80 kph

 

ADDITIONAL TIPS:

 

Careful driving during the first 2,000 kilometers will pay

dividends later on in longer engine life and smoother mechanical functioning.

Specific RUNNING IN, though, is unnecessary, but it bis advisable to

remember the following:

 

* Constant speed operation should be avoided as parts tend to quickly adjust

themselves to other parts if variable speeds are used during this

initial period.

 

* Severe brake applications should be avoided, if possible, during the first

150 kilometers of inter-city, 1,500 kilometers of highway operation.

This will allow the brake lining to seat against the brake disc and drums.

 

* Driving a car with manual transmission, you should avoid consistently high

speeds, over-revving, or straining the engine. Use the gearbox freely

and vary your speed.

 

* With automatic transmission, as well as oberving the manual transmission

recommendation, avoid holding on to the override positions for prolonged

periods, harsh engine breaking, or too frequent kick-down acceleration.

@john2004 - I couldn't have said it better, great post sir! Bravo!

good day... who knows an expert mechanic for honda civic 1996 vtec.... idling drops.... thanks...

possible source/s:

-the IACV needs cleaning...(a.k.a. throttle body)

-spark plug needs to replaced

-throttle cable needs to be adjusted

-fuel lines are clogged

-fuel filter needs to be replaced

help please..

 

toyota innova diesel experiencing occasional loose compression (not sure of term to use when you give it gas to no avail) while driving, specifically when slowing down, resulting in the engine dying out. after restarting the engine, it will run smoothly again for a prolonged period of time before the symptom reappears.

 

brought it to a mechanic and drove it with him a long way without the problem manifesting itself. mechanic said he couldn't fix it if he didn't know what he was dealing with and suggested i bring it to a shop with a computer-aided diagnostic machine.

 

if you have any idea what my vehicle's problem is, please share your thoughts. likewise, since i have been putting off the idea of bringing the vehicle back to toyota (for fear of exorbitant fees) prior to another try with a local shop, referrals to one (a car repair shop) in the q.c. area that you think will be able to help me would also be appreciated.

Possible causes:

Vapor-lock, but since the Innova has a commonrail fuel system, it's unlikely.

Faulty fuel cut-off switch

Clogged fuel lines/dirty or clogged fuel filter

Dirty air filter

Dirty air intake sensor

Problem with intake or exhaust valves

 

How old is the vehicle and how many kilometers has it travelled?

[kanski]

^

 

its a little older than 4 yrs and has traveled ~55k kms.

 

can you suggest a place preferably in q.c. where i can have those possible problems a look see?

 

thanks btw for taking the time to answer. really appreciated.

try bringing your car sa RUBBERVOLT WEST AVENUE bro, they have good mechanics there though mahal lang sila sumingil.....

 

just try it bro then decide for yourself....

There's another possible cause- fouled up injector or injectors.

 

So sorry, but don't know any good mechanics in your area. Hope you can find one who has a diagnostic computer for the Innova so you can be sure that it will be repaired correctly, rather than do a trial and error repair.
