Just repairing...

[Ryo]

Ok will check the cold start injector too, thanks for the hint.
Today will arrive Wix oilfilter and japanparts fuel filter. Hope the fulel filter will be ok. Now just i need new brake discs for rear. Lots of fakes are here is aftermarket shop so i must get some from specialists on tune up here. Looking for some zimmerman, ferodo, ate, omp or ctf. I dont trust those italy marks (Brembo, Bradi) they are usually fakes.

Ok hachi is running again . But there is still problem. The idle speed is really high, around 2100rpm. The main problem was bad ignitier. Dad repaired it really quickly (in about 20 minutes ). There is still problem i think it could be the air flow meter that is causing high idling. Because when i pulled the hose out of it the rpm dropped quickly down.

Received the ordered parts:
Japanparts fuel filter, ABS rear brake pads, Wix oil filter, gates alternator belt.

Is that your idle with warm engine?
If not, then that's a normal value..cold 4age's like to warm themselves up
quickly. Is the idle adjust screw turned all the way down? Are there any vacuum leaks, is the throttle plate adjusted properly?
Plenty of possibilities to consider. I wouldnt have expected the igniter too be at fault, but that's good to know in case someone runs into the same problems.

[Ryo]

No the ignitier was bad at begining so i changed it for one that was good running in my old hachi. I am sure it was faulty because after i replaced it the engine started to run normally and no shaking by acceleration. Now its just idling high and the idle adjust screw is all way down. I must look in manual and find what is wrong when i am back from work.

i am hapy to hear this good news.

[Ryo]

Ok i am now really out of ideas. The car is acting really weird.
Fuel consumption is 16L on 100km!!! Normally it should be 8L i think.
The car is poor accelerating and it is feeling that somethink is slowing it on driveshaft. Maybe it is bad? The car has already 443 000km on it.
The car is always going to PWR light. Weird is that if i pull hose out of the vacuum sensor the rpm drop down. If it is connected there is about 2100rpm.
I tried the idle adjust screw but it is already at min.
Waiting for your ideas . :wink:
I think soon i will change the whole engine bay from my old car

We had similar "Power light always" simptome once.
The MAP sensor tube was broken, one injector was clogged.
Can you check your injectors and fuel pressure regulator ?

[Ryo]

Hmm that's bad to hear. I checked already the resistance of injectors and they seems to be ok. I already changed the fuel pressure regulator too.
Hmm my power light is lighting only if i step a little more on gas. But truly a little. Is weird normally it should be lighting Economy by hitting the gas pedal.
Its really bad that i dont have digital camera . That way is to explain troubles a lot easier. I still can't name in engine bay a lot of things. Hmm MAP sensor what's that? and where it is located ?
Too bad that the manual on this page for the 4A-GE engine dont have the picture of the ae86 engine bay. There is only picture of celica, ae92 and mr2.

[Ryo]

Ok i decided to clean the whole fuel system and to check the injectors. I am gonna use the injectors from my old hachi. I checked too with some guy and he wanna sell the US version rear lights on this car and i can get from him kouki bumper on the front from wreck of some US version gt coupe. He has the japan styled sideskirts on it too
There is air flow meter too in it. I am wondering if the air flow meter is good or bad thing to have. Can anyone explain me that?

Unnecessary. To run AFM you will need harness and ECU from AFM 4AGE engine.
