dude_4_sale Posted March 11, 2009 Share Posted March 11, 2009 (edited) lets get started. i bought this 92 legacy wagon about a month ago. dude said it just suddenly stopped running. come to find out the crank key just broke so i replaced it and it started right up. he said that when he took it to the mechanic the tps, knock and o2 sensor were bad. he never changed them. after driving it for the month those codes have not popped up again. it is lacking some power and i have checked the timing several times. it seems to be timed correctly. just two days ago the check engine light came up. code 42 --- idle switch. says see chapter 4. i go to chapter 4 nothing there about it. when coming to a stop and the idle drops below 1k. no matter what i do. the throttle is dead. i just sit there sputtering. after a min or two it comes back and i can go again. need some help. where is this switch or sensor? -------------------------------------- ^^^^^^^^^------------------------------------------------ sorry found a few posts on how to fix this! will keep yall posted thanks. still need help on the rest. ============================================================================== also. from reading alot here. i have determined that when the awd is engaged the transmission goes into fail safe mode. cant go above 60, dah dah, dah. weird thing is. when i put it in fwd. it will go past 60 but still shifts really early and hesitates. unless i double pump the gas and hold it. then power mode kicks in and it down shifts. i know it shifts early for fail safe mode. but is it always suppose to shift so granny like? one more thing. when it does down shift or i ride the gears out manually. when there is load on the motor. both the battery and brake light come on. when i bought the car i changed all 4 rotors and pads, then topped off the fluid. i stop pretty quick. why are those lights coming on? thanks Edited March 11, 2009 by dude_4_sale Link to comment Share on other sites More sharing options...
OB99W Posted March 11, 2009 Share Posted March 11, 2009 For code 42, check operation/adjustment of the throttle position sensor (TPS). Battery and brake light coming on typically indicates a charge problem, often due to a failing alternator. I'd deal with those two issues first and see if the trans problem persists afterward.

dude_4_sale Posted March 18, 2009 Author Share Posted March 18, 2009 k so i fixed the tranny issue. the dead throttle is still happening. i changed the tps and the idle air valve. they were bad according to the book.:-\ runs better. once the car is warmed up it runs fine. but when the car is cold. the throttle is intermittently unresponsive. i have been stranded in the middle of a few different intersections. not good in traffic. really need yalls help. start naming things for me to check or replace and i will keep yall posted. thanks Link to comment Share on other sites More sharing options...

nipper Posted March 19, 2009 Share Posted March 19, 2009 Benchtest the TPS, and check the engine coolant temp sensor. Usually the CTS is responsable for repeatable oddness. nipper Link to comment Share on other sites More sharing options...
Cougar Posted March 20, 2009 Share Posted March 20, 2009 It kind of sounds to me there is a loose connection somewhere to the TPS sensor that may be causing the intermittent trouble. You might try checking the voltages on each of the pins while the engine is running ok to have as a reference. Then check the voltages when the trouble happens again.

crockettbrat Posted March 20, 2009 Share Posted March 20, 2009 Have you checked the smj? big mega plug under the dash (big grey plug with a bolt to keep it together), my ej brat had that smj loose which caused some intermitent problems. Good luck. Daniel Link to comment Share on other sites More sharing options...
dude_4_sale Posted March 22, 2009 Author Share Posted March 22, 2009 i havent had time to mess with it. will be goin down the list tomorrow. will be checking the tps again, cts, big grey plug, and the maf. will keep yall posted thanks again. its hard to check things when the problem happens. it only lasts about a min at most. and it always seems to happen in a busy intersection. it has a death wish.

Gloyale Posted March 22, 2009 Share Posted March 22, 2009 Have the fuel pressure tested. Sputtering under load is a sign of not engough fuel. I'd replace the fuel filter just on principal. It is super easy, just need a phillips screwdriver. it is the black canister right next to the drivers side strut tower. Link to comment Share on other sites More sharing options...
dude_4_sale Posted March 26, 2009 Author Share Posted March 26, 2009 so i even changed the ignitor just to be safe. checked all of the above and everything is fine. right next to or under the idle air valve by cylinder 3. there is the sound of something grounding out.(loud ticking or clicking) very noticable under load. i checked the spark plug wires but they seem fine. i havent had time to buy new ones and replace them. could there be something else under the intake right there grounding out. wires is what im thinking but i want to make sure before buying new ones. alittle tight on money. and these are practically brand new.

nipper Posted March 26, 2009 Share Posted March 26, 2009 Fuel injectors click. try disconnecting the injector and see if that sound goes away. Link to comment Share on other sites More sharing options...
dude_4_sale Posted March 28, 2009 Author Share Posted March 28, 2009 i didnt have time to pull the injector clip but i did grab the spark plug wire boot on the spark plug and i can feel the clicking as if something is hitting. i pulled the plug and its alil burnt but still in good condition. i will pull the injector plug tomorrow. any other suggestions?
