#1693 of 2067 having engine problems with my Tacoma
Dec 03, 2005 (5:48 pm)
dilemma, i'm here in a small Mexican Town and do not have access to a diagnostic computer or Toyota Dealership.
My 2002 Tacoma PreRunner D Cab 69950 (yes) Miles has started acting bad. The check engine light is on (though sometimes only flashing) and the truck sounds like it wants to explode at 50mph (coughing and poor handling, shaking). My suspicion is Fuel Pump, but I'm no genius, so I'm seeking any reccomendations that I can relay (in very bad Spanish) to a mechanic here, if anyone can help, Please!!!

Sounds to me like you have a missfire wich will make the check engine light flash.I would start with a tune up and hope that takes care of it.As far as it being the fuel pump....very unlikely as the Toyota pumps are bullit proof.Make sure you use the Toyota factory spark plugs.
#1695 of 2067 HELP!! Weak Brakes 98 Tacoma
Dec 04, 2005 (8:40 am)
I hope someone can give me a bit of advice on this topic. I'm going nuts trying to figure this out. Here's a quick synopsis.
It's a 98 tacoma 4x4, 3.4v6, TRD. Brakes have always been a bit week even when I bought it stock 3 years ago, so there has always been a problem, now that I have 35" tires obviously that emphasized the problem.
Rear brakes didn't seem to do anything so tried adjusting proportioning valve armiture. No luck, changed proportioning valve since it look pretty beat up from something. Some difference, not much.
Thought it might be the booster, so had a shop replace that. No change in braking power. Shop said because of my supercharger I had a decrease vacuum. Ok, understandable even though I was still pulling 15 (inches??), so to correct that I installed a vacuum canister. No shortage of vacuum now.
Front rotors were warped, so I installed some slotted/drilled baer rotors and high dollar pads. No difference yet. Just changed the master cylinder, still no difference. What the heck am I missing here!
And for those of you that think it is the larger tires, I disagree. My braking power is so bad that even with stock tires I roll right through stop signs in normal braking.
The calipers look fine, no leakage or rust. Before I waste money to replace them with no difference, I was thinking to go to a Big Brake system, but don't want to spend any more money with out some expert advice. Please HELP! Thanks.

I am a mechanic by trade, so perhaps I can give you a little insight. I would really like to see the truck before I make a judgement, but that is likely impossible. I had a 96 with no brake problems at all, so I know that it is not a normal thing for the Tacomas. It sounds to me like you have a lack of power to the entire brake system. It is either a bad power booster, lack of vacume or a vacume leak. Could also be that the vacume hose is connected to the wrong place. Some ports have vacume when the engine is idling, while others have vacume at cruise. You can have great vacume at the port, but if there is none at idle, it will do you no good to have a 50 gallon vacume resevoir. You always brake with the throttle closed, so that would explain if you have the wrong port. If you can get your hands on a portable vacume pump, run a hose into the cab and pump up the vacume while trying to stop. If that don't work, then it is likely the booster that is bad. It really soumds like you lost the power part of your power brakes. If you are not locking up the rear brakes, there is a definate lack of power. The front brakes do most of the work, so a problem with the rears would be minimally noticed and a problem with the front would make the rears work harder and lock up. If you are noticing a fluid loss, then it could be other things.

I completely agree with you, it just doesn't seem right that's why I'm so frustrated. The vacume port I'm hooked up to is the one which the Supercharger instructions showed, plus it is definitely pulling plenty vacume at idle. I've been fooling with the rear brakes with the rear tires in the air. Found that the proportioning valve wasn't adjusted properly anymore (bent arm from something). Rear brakes actually stop quickly now with the rear tires in the air.
I haven't test drove it yet, but it still doesn't feel like there is enough power to the master cylinder. It only takes a very little pressure to the gas pedal to get the rear tires spinning when the brakes are pressed fully.
I couldn't lock up the front tires at all, and definitely no fluid loss. I'll try doing the remote vacume test after this test drive. Thanks for your advice. If you have any more, I'm all ears.

I would check for kinked or pinched brake line tubing or hoses. Warped rotors may indicate calipers not fully releasing quickly -possibly due to pinched line restricting flow of fluid back to master. Would also slow brake response. May be a long shot, but replacing tubing or a hose is cheaper than most other components.
I'm especially curious about piping damage because of your mention of external physical damage to the proportioning valve.

I looking at a 1995 Toyota Pickup DX that's for sale from an individual. The guy said the only thing wrong is that the previous owner disconnected the parking break handle (because he didn't know how to use it?). So the handle is in the cab laying behind the seat and he said all that needs to be done is to put the handle back in and reconnect the cable to it. Is this an easy fix? I'm fairly handy with my cars, can I do this fix myself?

I've noticed a vibration/shuddering on my '06 Double Cab around 5-10 mph when decelerating somewhat quickly. It feels like it is in the drive train somewhere. Of course, the dealer didn't feel it. Not knowing what it is, I'm a little concerned about potential damage somewhere down the road. I've also noticed a little hard shifting in slow and stop and go traffic conditions. My last vehicle ('00 Dakota) was smooooooth. So, I'm a little concerned. Other that, I love my new truck.
#1701 of 2067 dissapointed in my 05
Dec 09, 2005 (9:49 pm)
i am very disappointed in my 2005 Tacoma Access Cab with the TRD Package. i bought this truck expecting to be able to go off-road with little to no problems and the skid plate on the underside made me pretty happy b/c there are a lot of things on trails that can really mess ya up. i took it off road on a TRAIL (nothing harsh) ONE time and that one time something came up and punctured the radiator. the check engine light came on and i took it to a toyota place the next day not know it was the radiator and by that time everything was gone. i am having to replace the small block and heads on it...labor and all it almost $10K,insurance wont help and toyota said they cant do anything either. i am not sure exactly what the purpose of skid plate is if it isnt protecting the things that need protecting the most. this is my first toyota and probably my last.

Sounds like you and I may have the sampe problem. My 98 Taco has been intermittently failing to start. I can hear a click when I try to turn it over, but other than that there is no sound at all. After one, two, or three attempts, usually a minute or so between attempts, it will turn over and runs fine. I was told to check the 80A fuse under the hood, which appears to be fine. As of this morning however, it will not turn over at all, no matter how many attempts I have made. Anyone have any other suggestions as to what it might be? Thinking at this point it must be the starter has gone out.
