2nd gear bogging down "clogging up"

[keiichi]

have this really wierd thing wrong with my car... every gear is fine except for when youre in second if you flatten it power is severly reduced until about 3500rpm then the power kicks in again, i think that it also caughs out a chunk of smoke, not sure on that though... it has done this problem in the past but saughta went away after awhile.

a pre thankyou http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

weird....

[psychofox]

gee lots of information for diagnosis right there.
For starters What car? What engine? What ECU?

If you give crap information people can't diagnose anything. If you notice threads where people provide good information up front - they get a better response.

[keiichi]

right yep yep sorry chill out lol...
its a toyota corona 1985 with a 22re stock ecu basic breathing and exhaust mods and an oil catch can. gearbox is a W58 i think... the big fukin strong one... think its the same as old supra and hilux.
anything else let me know

[mattysshop]

check plugs, and fuel filter.. (check meaning change!!)

usually you need to go through a few steps to eliminate possibilities.. also consider dumping an entire can of carby cleaner through it's guts, and as many of the emmisiones lines/valves you can.. don't be scared to go crazy with it.. and it will idle very shitty if at all for about 5 seconds when you first start it after giving the throttle body etc a good working over with it..

[mattysshop]

also an injector cleaner after those wouldn't hurt.. prolly get an extra 50-60km's per tank after all this anyway!!

[Cerby]

sorry i have to say this....you have a corona! They came from factory with an engine which sounds on the verge of death yet never quite kicks the bucket!!
sorry but after reading the other problems that you are having with the car i just had to say it!!!
Now being helpful i reckon it sounds like it is either getting to much fuel or too little air. do the stuff mattyshop said becuase he actually knows what he is talking about then check the ignition side of things. if it is ignition it will be dirty plugs but also check that the coil is firing properly.....hold the business end of the center lead and get a friend to turn the engine over. Voltage is measured by how far you get off the ground.
Also try wandering into a mechanics and getting them to check over the car....make sure you tell them how you held onto the coil lead, it will make them like you!!! Seriously tho did you get the other problem you had?? If not take it to a mechanics cos there is definately something wrong with your car!!
Cheers

HAHAHAHAHA!!! i'm using that one!!!

[rthy]

yeah the funniest thing is i know someone who actually used this technique when trouble shooting the engine on a bren gun carrier.....but he was a nutter anyway!!!
Also i'm kind of feeling a bit silly cos i just realised that i mixed kiechi up with some other fella so just ignore what i said about the other problem you had with your car cos it is entirely possible that you didn't actually have one!!!!!!
hehehehehe i'm soooooo silly (tool)

Well spoken Cerby

"how far you get off the ground" i must try that one as well.

Your problem, sounds like what mattyshop has suggested.

Just an out of tune motor. Mattyshops ideas will/should help with your delima's.

Speaking of which, i must change my fuel filter.

[keiichi]

alright sweet thanx people ill check all those thingys and let you know how it goes. the car is EFI btw if that changes anything.

cerby. thanx for the rave lol. ill put my TOUNGE on the 12000 volt spark and the faster i die the better it is.

about the carby cleaner, do i just take off the pod and spray it into the front of the airflow meter? how many revs should i do this at? the injector cleaner is just the stuff you put in the tank eh... what brand is best?

[riceburner]

i would take off one of your inlet manifold hoses and throw it in there, and for reference you can use fuel system cleaner the same way.

I prefer to use Nulon products but its up too you.

[keiichi]

at how many rpm should i do it?

[riceburner]

at how many rpm should i do it?[/b]

2500-3000rpm for roughly 3mins, engine will probably cough and splatter then should free up over time.

I wouldnt constantly spray the carby cleaner either, only like 20sec bursts then rest then go again.

Or you could start slow and work your way up. Dont forget to thoroughly clean your throttle body. Take it off and clean allports as well. Wouldnt hurt.

There was a thread on cleaning throttle bodies somewhere

[mattysshop]

wow.. wait.. don't do it while it's running! http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif you can... but no point.. take off your intake pipe air flow meter etc.. and spray it directly into the throttle body so you can see it cleaning all around the butterfly, and in all the nooks and crannies inside the throttle body, the PCV valve should also be cleaned.. this will be somewhere between the oil breather and the inlet manifold.. usually it's on the inlet manifold..

hold the throttle body open the continue spraying the carby cleaner inside to clean as much of the brown staining as you can..

Nulon Total Fuel system cleaner FTW!!! but you should change your fuel filter and spark plugs first.. to get the best effect..

[keiichi]

sweet as fuel filter is about 1 month old so no nead to worry about that... spark plugs are about six-nine months old should i worry about them?

[riceburner]

wow.. wait.. don't do it while it's running! http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif you can... but no point..[/b]


My point was to give the valves a decent clean. i assume he wouldve clean the throttle body whilst he was at it.

And yes i wouldnt clean the throttle body whilst engine is running.

Slight mis-calculation of words there i think.

[mattysshop]

if they are shitty copper core ones yes..

iridium NGK's FTW!!

[keiichi]

are you saying i should use the iridium spark plugs?

btw... used a whole can of carby cleaner and some injector cleaner OMG its made such a difference... engine even sounds deeper. thankyou all for your help http://www.ae86drivingclub.com.au/forums/emoticons/biggrin.gif

[keiichi]

oh and the fuel filter cost like $25 reackon it could be a shitty one?

[mattysshop]

yes.. iridium plug last upto 100 000km's ... so what if they cost you more right now.. if you work it out they are cheaper in the end http://www.ae86drivingclub.com.au/forums/emoticons/wink.gif liek the whole reusable cotton filter scenario...

the fuel filter nar thats pretty normal.. there not expensive.. thats why you should replace them prolly every 15 000K in an older car (scale and sediment in the bottom of the tank) doesn't hurt what soever serviceing and maintining your car as often as you can..

has this fixed your problem though??? or atleast made it a wee bit more responsive??

[keiichi]

oh man its fixed the problem alright... i couldnt believe how much crap came out. it literally took the whole can almost exactly before brown shit stop running back out the throttle body. well car runs smooth again and sounds deeper and is generally more powerful. its like i got a little bit more volumetric effeciency (well did actually). canned HP, i recommend it alot http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

If you run a oil catch can type of system you will have to do it less frequently, and by the sounds of it, its never really been done before.

Its one of those things that should really be done every 2nd oil change.

[keiichi]

yeh i know what you meen... i do run an oil catch can now atleast so should be sweet.
