Replace your spark plugs and PCV. It's the cheapest possible solution. If that doesn't suffice Acura had a recal on EGR valves a few years back. I would suggest getting your EGR valve changed. It's not expensive and it's easy to get to. It doesn't take more than 10 minutes.

Seems like you may have a fowled plug in there, changing your spark plugs should cure the rough idle and may even turn off the engine light, as for the traction control there are sensors on each wheel hub with a wire possibly 2 going into them, take a quick look and make sure none of the wires have any breaks in them or broke completely, or the tsc module itself may need to be replaced,
the car is perfectly fine to drive as is, until you can get new plugs, rough idling is normal and may make it a little harder on fuel then normal,

SOURCE: Check engine light + TCS = braking vibrations

You need to get to a repair shop and have them read the diagnostic codes (the computer port is in the center console under the change holder/lighter). With that amount of mileage, it is very likely the code will show that the oxygen sensors and/or catalytic converters need replacement. If that is the case you will also need a tuneup (plug, wires, etc). I had this done a year ago at 160,000 miles. It is a pricey repair but I get 29mpg at highway speeds and it runs nicely on regular (less power but no pinging).

The TCS light came on and the car started jerking especially at stops. The light would go off for a while after restarting the car but the same problems would happen and the light would eventually come...


The TCS stands for Traction Control System, I believe. The TCS is controlled by inputs from the wheel speed sensors. If you have a bad sensor, then a new hub may be required to repair it.

The check engine light may be a sepawrate problem. Have the codes scanned for both the Anti lock braking sytem, TCS, and the check engine light.

Sometimes it will require a separate scanner for the TCS/ABS vs. the Check Engine light.

Good luck on this diagnosis and repair.

Tcs light, check engine light flashing and constant shaking..


Use an OBDII scanner, some auto parts stores will do this for you free of charge.
Codes P0300 through P0306 indicate mis-fire and you may also get codes reflecting Cat damage from running that way.
I know of one TL from this series (2000 3.2 TL) which had a warranty REPLACEMENT OF TRANSMISSION!!! free of charge and this very problem was solved. I still do not know why they were related. Talk to Acura customer relations about this.

2002 Honda Odyssey TCS light comes on after driving approx 1 mile


There are several things that will turn the check engine light and TCS light on .If you get the code I can tell you exactly what the problem is . On your year i see transmission problems as well as EGR problems. If you go to any large auto parts store they will check the code for free or a very small fee.

99 TL engine roars and shakes when pressing on gas.


a flashing chack engine light means you have a catalyst damaging misfire the tcs light comes on because this system will not function with certain codes stored for the engine or trans. knowing that you have a misfire you very well could have a bent valve the question is why. have someone check the engine timing incase the timing belt tensioner has failed. i have seen this happen on the 3.2 before or a burnt exhaust valve . as far as the distributor goes the 99 tl does not have one it has cop (coil on plug ignition) . this means you have a seperate coil on top of every plug one of these could have failed check the code to see if the problem is isolated to 1 cylinder rhen start looking at that one and you better hurry that light flashing means you will damage the catalitic converter if the car continues to skip good luck and i hope this helps you.

TCS and Engine Light are ''ON''. Engine misses badly.


A part is most likely malfunctioning causing for the TCS to turn off. You'll have to get a diagnostic check to determine what part is failing. What ever that part may be is causing for the misfire.

Tcs light flashes


if you're flooring the car and there's wheelspin that will activate the tcs, which stands for traction control system. It cuts fuel to slow you down until you gain traction. So no burnouts on the TL. =D
