Hey guys, My car is having a little trouble atm...Just wondering if anyone has come across this b4..When travelling at say 80k/s or under, my car is fine.. but when i put my foot down past 4000rpm/or 110kpm, the taco goes spastic, and the car coughs and jolts around.... i have changed the fuel filter, and oil filter. i bought some fuel injector cleaner but havent tried that yet...Could it be the fuel pump? Also i havent gotten anyone to drive behind me yet to see if it smoke at all, i know it doesnt when it idles/drives fine, but when its hiccupping, i dont know...this engine is a ej22, gen3series2(or gen2ser3, cant member) 96 model anyway....Thanx guys..any input would be greatly appreciated... i hope its not too seriousCheersAdam

hey mate,

Check your error codes, to see if you're getting a Knock Sensor problem?

Does it start pinking just before it coughs and jolts?

sorry, pinking?? pinging??no dont think so

MT? could the clutch be slipping? maybe it's worn out or some oil is on it?

 

I dunno

sorry 4 speed auto

The erratic tach makes me think you may have a problem with the crank sensor.

im unsure what that is:(i will check the ecu tonight for any codes

The crank sensor monitors engine speed for ignition and fuel injection timing. It's located at the front center of the engine, just above the timing cover. You may be losing RPM signal from the crank sensor at higher engine speed.

thankyou...also can someone please tell me/show me what a knock sensor looks like so i can locate it and test it??Thankyou

Is there a way to monitor the voltage? maybe the alt is cutting out or, as suggested , some kinda wiring, grounding problem. maybe pulling, pushing, bending some wiring harnesses at idel would help find the general area that causes the problem.

 

interesting

this topic sounds pretty close, i will try all on here later..cheers guys..http://www.rslibertyclub.org/forums/showthread.php?t=56489

Well i figured out the problem. i had a look at my knock sensor, that was fine.... then i decided just to tinker about and check all my connections... i found this... i wsant sure was it did or was(still dont) but i saw that the plastic surrounding was broken and the plug was loose.

i wedged it up so it was tight, and took it for a spin, didnt miss a beat....

now i need to either get a new surrounding, or super glue it back together..

here are some pics... Ther red bracket is whats broken(between the bolt and plug)

 

here is the plug

 

Here is it unplugged

 

Here are where the plugs are..Note the plug surrounding that is broken is the lower right one

 

 

And here is just a pic of my car(with temp quarter panel..just testing snorkel)

 

 

also, sorry bout dodge pics, there from my camerea fone..

Hey Fatz, what car is your Snorkel off matey?

Lots of Aussies looking for a snorkel to suit their Foresters these days.

That is the cam sensor. It tells the ECU whether the #1 cylinder is in the intake or firing position. It uses this info to fire the injectors in the correct sequence. Since Subarus don't have a failsafe mode (batch fire injection), it won't run without it.

i am pretty sure it was made for a lseries.....not too sure if it will match up to a forester or not tho... i will find out for you tho if you like.....

ohh and thanx heaps drx
