Toyota Fielder Car Help

[azlan]

I have a toyota Fielder PCK. Bought it 2 weeks ago. The engine had sludge and I was getting a grating noise when I start on mornings.

Went be mechanic he removed the crankcase and strainer and removed most of the sludge. The noise reduced tremendously..... But it is still there occassionally.

I did a full tune up but the car started to buck very badly. I went by speedy in bamboo to diagnose the prblem only to realize that the parts place sold me the wrong size plugs and one of the ceramic in the plugs cracked so current was leaking out causing the car to buck. I changed the plugs and that problem is solved....

I am now experiencing a sort of delayed reaction when I mash gas... Its nothing major as the car is powering up fine and is not bucking but I copuld be wrong but the car seems sort of sluggish at times. When I am at a stand still and the RPM is at 1 and I mash down on the gas it kinda stalls for a second then shoots off..... Is this normal?

The mechanic told me he cleaned my injectors manually with spray but I do not think he used the pressurized machine. Could this be the problem.

Should I even bother about this? I let my wife drive the car to see and she fine it is working fine but I drove a fielder before and I dont find it is at its optimal potential...

Let me know your thoughts......

There can be a number of factors. Firstly, if the mechanic use the wrong plugs, chances are he may have only clean the outside of the injectors and not the inside, which is most critical. Also, these cars intake manifold are plastic and tends to get very dirty as well. The trotttle body also needs to be throughtly cleaned. The TP sensor is located on the trottle body and if the trottle body is dirty, the trottle responce will also be delayed. And finally, those engines are VVTI and 30 body oil is the recommended lubrication for this engine. Use only 5W30 or 10W30 oil only. If you believe that the car is not performing as it should, take it to an automitive technician and forget those so call mechanics

Praise.... You real knowledgeable hoss. Do you run a garage? I started to go by Speedy garage in Bamboo. Are you familiar with them? Do you recommend them?

He mentioned to me that he might have to clean the trottle body and that makes alot of sense what you said. Do you suggest that I clean the injectors properly first and then wait and see if the performance increases? or do the trottle body one time.

How much on average does it cost to clean the trottle body? He quoted $350 to clean the injectors with a cleaner and a 80psi machine?

Let me know your thoughts praise....

No I do not run a garage nor am I familiar with Speedy garage in the Bamboo. It would be better for you to service both the injectors and trottle body together. The disadvantage of servicing the injectors on the car, is the oil gets contaminated with the chemicals that are used to cleans the injectors. Because of the nature of the chemicals used as well, the extra heat generated causes your spark plugs to disentigrate. It is adviceable to do it just before an oil change and it is also adviceable to replace the plugs after or put in old spark plugs for the servicing. Seeing that you just change your oil and flush your engine, wait until the next oil change or get the injectors and trottle body removed completely from the car and get it done externally. The cost varies according the the method used and the garage you take it to. But do not be fool into believing that the higher the cost the better the service. Check around so that you can have an average cost. I hate to see people being rip -off of the hard earn cash. You can check Anil Sooknanan, a member of this forum to do a proper job for you.

first ting i suggest is cleaning your MAF sensor
also if the engine in such a bad state check your tranny fluid and see what it looks like.
change the air filter also.
is the car ethrottle or cable throttle? dont mess with an ethrottle on your own
1 change air filter
2 clean maf
3 reset ecu (disconnect battery)
if this doesnt help then move to cleaning the tb (only if cable)

The Garage's method of cleaning the throttle body and injectors is done while the parts are still on the car. He said that the correct thing is to change the oil and filter after the chemicals are used. He puts on old spark plugs for this job if your plugs still have life in them.

He told me that since I olny changed my oil last two weeks then I could either wait until the next time for oil change to do the work or I can do it immediately.

He said that the oil does become contaminated with the chemicals but it also acts as a detergent which will assist in breaking up any sediment from the sludge as well. He said that no damage will be done if I do not change the oil one time since I just changed it two weeks ago.

I have new plugs in the car now so he said he will put old plugs in to do the service.... Let me know if this is correct.

Can any harm be done by me not changing the oil immediately??? I was thinking to wait like 1500 km after he does the service then to change it. Remember that my oil was changed twice in the last month in an effort to remove aludge from the engine.

^^^i worked in an auto garage, everything said by praise and cinco is adviseable, very good advice, follow it up and ur car should be working well...

[Anil_Sooknanan]

what he said is true about the chemical stuff. by chance is your wagon E-throttle, which i think it is. how did they go about cleaning the Throttle body? it sounds like the throttle plate sticking or the magnet weak and the vacuum pressure holding the plate closed until you apply the pressure on the peddle to overcome the vacuum pressure. Praise you know your the expert here with the qualification and certification of a auto technician. what do i have

oh and you won't believe which garage he running
