Car hesitate when accelerating (CLS 6MT)
Hi guys, my car have a little problem... when i accelerate, my car seems to hesitate a little.
But everytime i reset my ECU, the throttle reponse is DIRECT. Gas padal to the floor, the car reponse is immediate.
But after 1-2 day after reseting the ECU, the throttle reponse is much slower.. why? it took maybe half a second more to accelerate when i put the gas pedal to the floor.... and the car hesitate a little..
Why? can someone here explain me this? And im sure im not the only one here who have this problem.
Thanks!

Test your TPS. At closed throttle is should read .5v and wide-the-fuck-open it should read 4.5v.

Do you have a multimeter?
Put the positive terminal on the middle wire. Many ways to contact it. Try using a paperclip in the harness clip until it contacts the connector, then touch (or clamp on the alligator clip) your positive probe to that. Negative connects to ground. Turn the car to ACC, and see the reading at closed throttle. Should be ~.5v. Then open throttle all the way and it should read ~4.5v.
You can adjust it if your readings are incorrect. Just loosen the screws and twist the sensor slightly and check the readings again. Once the readings are in spec, tighten it down.
If your TPS is really shot, you can pick up a new one on eBay for cheap. I used one of those in my old Civic.
BTW, Im not sure if Honda still used rivets to attach the TPS on the CLs. If so, just dremel a slot on the cap and you can use it as a flat head screw.

You cant switch out the TPS to my knowledge, I'm pretty sure it uses those annoying rivets that lock them selves in if you drill them.
I think you have to switch the whole TB. (I could be wrong)

Thos rivets arent really rivets, they're break away bolts. Once they tighten them down, the head snaps off, much like the bolts on the steering column for the ingition cylinder. Just dremel a slot large enough to fit a flat head screw driver and you can unscrew it.
That isn't a J series throttle body, but the sensor is on the left while the linkage is on the opposite side.

Thats what the dealers like you to think!

Blox and few others sell just the TPS for $40 or less, to replace it take a dremel tool with a cutoff whell and make slots in the two headless crews then back them out with a flat blade screw driver, install the new one loose and get a multimeter of can tool, with the ignition on and the throttle closed you want a .4-.7V reading, once you have that tighten the screws the rest of the way. Also the screws are 5mmX.7mm thread some places will have them, so I would replace them with convention headed screws or bolts.
