1. Someone explaint this to a newbie like me would you? I see the diagnostic port but the local parts store cant adapt to it. Is that what its about?

2. My 87 4runner is hessitating when I gas it. Itll go brrrrRRRRRRR then get on up with no problem. Stick me with a fork and call me stupid but I cant see a fuel filter anywhere. Thanks fellas.

3. Go ahead and make fun of my brrrrRRRRR, it just might make someone laugh today that had a bad day ya know? Even me.

 

Most of the code readers only work with OBDII, found on 96 and newer vehicles. If your check engine light is on you can get the codes with these instructions

If you have 4 cylinder engine I think the fuel filter is underneath one of the manifolds. I'm not sure though, all my 4Runners have been V6 powered.

 

Fuel filter is hidden, it's mounted to the inside of the frame somewhere between the gas tank and the engine, most likely(?).

The diagnostic port can be used to check codes by shorting 2 of the connectors, using a short length of wire. This will set the "check engine" light flashing. The number of flashes before each pause in the flash sequence coresponds to a number. (2 flashes then pause= the code 2 etc.)

I need to know what engine you have to tell you what 2 ports to connect with that wire. Then I can decode the flashes for you. Never mind just read that link, I was typing when he posted that up.

 

Wow, awesome site guys, thanks so much.

 

If it's a 4cyl., the filter is on the pass. side of the block, somewhat below the starter.

 

Seeing how Im caring for an 8 month old full time, you just saved me valuable time thook. I hope something really great happens for you bro. BTW, yeah its a 22re.

 

Mine did this a couple months ago, and it was the O2 sensor, nothing big, but the hesitation got so bad that i had to floor it to get anywhere!! It was funny though cause at the same time the transmission was going out and it would have to start in 2nd and go to 4th and 5th...Talk about bad performace

 

The fuel filter is not located in the frame rail. It is not located under the starter.

Eric the Red was right, it is located under the intake manifold.

 

Joey,

Use a paper clip to jump the TE1 and E1 connectors. Turn the key on and count the flashes. The CEL does not have to be on to have codes stored.

Here is the section of the manual that explains how to do it and what the codes mean.

And here is another manual link. Look in the Emmissions links to get information on how to test the sensors, like the O2 sensor.

Good luck.

 

The only filter under my intake manifold is the oil filter. I thought the fuel filter was attached to the frame under the car???

 

I have an 87 4Runner and I have been battling idle problems for weeks. I can assure you it is under the intake manifold. I have now been through the O2, plugs, wires, timing, timing chain, and am now in the process of checking the TPS, AFM, and EGR. As soon as I press the gas it disappears also. Maybe we are having the same issues. By the way, when I used words like , vrrooom and plooop, people gave me crap, but hell that was the only way to explain it.

 

Passenger side under starter. put mine in last month

 

brrrrrrRRRRR! hahahaa

 

The fuel filter is indeed under the intake manifold. It's sort of behind the oil filter. The easiest way I've found to replace it is to remove the passenger side tire. There is an access panel that can be removed from the fender well. Then a few different extensions and some scraped knuckles will get it done. A bright light helps too.

It would be a lot easier if it were along the frame someplace but some Japanese engineer decided this was a better spot.

Here is a not so good drawing of where it is located.
