hey everyone

 

at high speeds 110+km/h my car seems to jerk/lurch forward and the rpms go up and down....it happens around 3-4000rpm. I dont know what it could be....transmission....i thought subaru trannies were bulletproof?....is it the engine or just a stupid symptom of a faulty sensor

 

HELP!!!!

Maybe the spark plug wires are breaking down.

Throttle Position Sensor. it's like a rheostat. it could be bad in that spot you hold the gas pedal to maintain 65 mph or maybe when they did the headgaskets they knocked it out of adjustment. just a guess, could be many other things...........

A fuel pump can cause the type problem you are having.

 

A TPS is the throttle position sensor. It is a variable resistor. As the gas pedal moves so does the voltage from the sensor. I think the lower the voltage goes the faster the engine revs. It is backwards what you would think it should be.

 

Places like Autozone will read the codes for free.

Yes, try what the person above me said. If you put the car in 3rd, the torque converter won't lock up. If it does it still, then I guess it's a TPS or ailing fuel pump or something electronic.

 

If it doesn't do it in 3rd, might be the torque converter....

 

65 mph in 3rd is like....5000-5500? I haven't really got on the car lately to check. I do know though that on 4.11 gear, the very top of 2nd is like 60 mph.

like what?....the engine light is on but it'll cost me 75 bucks to get the code

i dont know where to go to get a reading for cheap im in toronto canada by the way

 

That much!! i drove out to missasauga, thats my favourite dealer, that subaru over there is the best!! i think it was 20bucks for me, but i know the manager, hmm, where else? hmm. Well u could jsut try shifting to 3rd to see what happens, but it really seems like it aint a torque converter, i think its a simple issue, does it do it with cruise control?

wow... you guys pay for that up there? I've never gone to a dealership but on other newer vehicles I've had I've always been able to go to any parts store and had it done for free. Doesnt make sense making you pay for that service considering all they do is hook up their tester thingy to one plug on your car, takes not even a minute, and that you're mostly likely going to buy whatever it is you need to fix your car through whoever pulled your codes. But then again its been a whole 9 months since I've owned a newer car with a computer so I guess things may have changed... :-\
