Question about 1995 Toyota 4Runner

1 Answer

Lack of Power

I have a 95 4Runner SR5 V6 auto trans w/185k miles. It acts like the engine is really straining to get up to speed. Almost like the exhaust is plugged, which it is not. I want to tow a trailer to pick up a truck(not running) I'm buying, but not sure if it will. I have had a recent tune up with all new plugs wires, dist.cap air filter. Any suggestions?

    I have checked the brakes already. Thank you

  • Biker02 May 18, 2009

    Actually ran about the same. I did check to make sure new parts were installed. Thanks!

  • Biker02 May 18, 2009

    No I have not. I did not know they did that for free. I was assuming the shop I took it to did that, but I didn't ask. I will make sure and do that. Is their a particular code I should be looking for? Thanks!!!

  • Biker02 May 18, 2009

    Yes the diferential fluids are all good. It really sounds like the engine is straining. It does get up to speed, but just does not accelerate strong (weak midrange). I don't know if this is charactaristic of that model. I guess I should probably check the compression which has not been done. It doen't smoke, but uses approx 1qt every 3,000 miles. Thanks!

    Have you tried stopping at autozone or pep boys & get free code scan done just to see if any come up?

    Sure you haven't got brakes holding? Drive a while & get out & touch rims carefully to feel for excessive heat at any.

Could be one of many but it may help pinpoint problem area better, if there is any codes.

Why does my 1992 4runner die when I put it in gear?

that could be an air/fuel problem ,does the engine rev ok when not in gear ? if it does then probably not air/fuel. the autobox speed sensor might be the fault have it checked at a auto trans repair shop

I notice that if I try to give it too much gas too soon it acts like I am overdoing it, when really I am not. It seems as if its pulling/straining to go at maybe 20 mph. Eventually, it gets up to the speed...

Have you checked fuel pressure yet ?
Assuming the check engine light is not on, my first guess would be low fuel pressure or an exhaust blockage.

My toyota 4runner. 1997, choke stopped working ( its a auto, 3.4 petrol SR5 V6)

There is no choke on these vehicles any more. Choke for lack of a better word is regulated by the uses references from the Engine Coolant Temperature (ECT) sensor and Intake Air Temp. (IAT) sensor to tell the computer how much air and fuel to mix at start up. At a cold start, the mix is more fuel....less air. Do you have a hard time starting your vehicle in the morning? If you have and "engine" light on in your car?

Ya sounds like the electric shift solenoid. Problem with electrical. Will not give you a warning. Will go bad in a heartbeat. You can try unhooking plug that gos into the trans and spray electrical cleaner on it. plug back in. Wiggle some wires and maybe find one loose or broken wire or connection and hope for the best. But its probably the tranny with that many miles. Go to Advance Auto Parts they usually scan your car for free for codes. Good luck

TCS light comes on

the tcs is ur traction control system this reads the wheels and if one slips cuts down power to engine so as not to damage engine or trans also if awd will activate the other wheels for traction the sensors are usually part of the abs[anti-lock brakes] check connections and wires as well as the sensors at the wheels and transmission -since the light is intermittent which would indicate a short or a sensor is about to fail the vehicle will store the code as pending -have vehicle scanned some auto stores do this for free such as auto zone/ advanced auto check ur local area the code will tell u where the problem is coming from

your local exhaust shop can perform a simple and free test to see if the cat can is plugged.

Hard to start when cold

your fuel injectors are worn out maybe. now and days they fixed this problem to withstand cold conditions but not in the 1990s.

1991 toyota 4runner sr5 3.0 v-6

i had the same problem after spending $500.00 for toyota to look at it they didnt fix it and suggested i it was the auto trans and i should get it overhauled costing thousands. i didnt believe them and started to do some of my own research into the problem. the coolant temp sensor at the rear of the intake manifold tells the ecu when the engine is at correct operating temp then allows the auto trans shift into overdrive. to rule out any problems with the auto trans i disconnected the plug to the temp sensor and went for a drive when the engine was cold and it shifted straight away into overdrive no problems. you can't leave this disconnected because the engine is hard to start when cold as the temp sensor also tells the ecu that it is cold and allows the cold start injector to inject more fuel into the engine on cold start overcome this i cut the wire to the sensor plug and installed a switch which i installed into the centre i start the car flick the swith use overdrive then swith back to normal after car has warmed up . engine fault light appers on dash when switched on but doesnt matter. i have had this modification for 2 years now no problems.
