Sorry forgot about this thread.

Fixed by getting a used OEM TPS. Blox one obviously sucked.

Im bringing this back from the dead.

So I have seen alot of things that sound like what my car is doing and alot that dont.

These are the possible senario's that cause the "Bucking" from what I have gathered here and from personal experience.

1. Incorrect or untuned low speed fuel map.

2. Bad TPS sensor.

3. Bad TPS sensor wiring.

4. Bad Dizzy or Coil or both.

5. Grounding problems (Which sounds like what may be going on with my car)

6. Bad IACV.

7. Bad CTS.

It seems that all of those things tent to affect idle and throttle position signal to the ECU in some way shape or form. I didnt put vaccum because that wasent anyones problem.

My TPS sensor reads the right voltage at closed and WOT when the car sits still in the driveway, If any kind of vibration hits the car (Someone sits in it or bangs on the dashboard) My TPS voltage will jump almost a full volt and not return to normal voltage unless I switch the key off then back on again. Weird! I have no CEL codes if I drive normally, But when I floor it and hit VTEC, I throw a code 7.

Im not sure what my problem is, But im curious to find out what ground was bad that AbsolutCobra was talking about.

this problem sucks !
ran fine when i have my b-series in my obd1 90 civic.
but now that i have a single cam ( d16a6 with obd1 DX ecu, dizzy and o2 )
i'm having this gay problem. it runs fine with the TPS unplugged and jerks/bogs with the tps plugged.

i've been reading this thread for a while now and tried almost everything i could with the single cam ( had the problem for about 2 months now )
i even swapped out the crappy a6 intake manifold for the sexy Y8 manifold ( 96 model no air injection crap ) AND no, i still have the problem.

any other ideas?

cliffs:
ran fine with obd1 b18a1, no cel TPS plugged = ran perfect
now with obd1 d16a6 (obd1 DX parts) rans ok with tps unplugged but runs like chit with it plugged.

recently i started getting the same symptoms, bugging at low throttle but if i open the throttle half away and on the car wouldn't bug. Luckily on hondata you can see the behavior of the TPS from smanager. From dead stop the tps is at 0%, if i slightly open the tps it would record 2,3,4,5% drops to 0% then goes back to 4,5% and on. It's like a dead spot.

I plugged the hondata on other car just to confirm the TPS failure, the recording where more stable, no bouncy numbers just smooth reading. I'll change the TPS and see if this issue is resovled.

BTW blox and omni get the TPS from same source the only difference is the sticker and the price.

my g/f is having a TPS problem on her 2000 GS-R, we bought a new blox tps but it didnt do anything,i want to try to re-wire it directly to the ecu,i found the pin-outs online,but i need to know which one is the signal/ground/volt.....**** sux

i got the new blox. it worked like a charm.

I had the same problem with my d15b7 in my 92 hatch right after I boosted it. I've had the TPS CEL for about 6 months, but it never affected the driving. Literally, as soon as I put the turbo kit on and drove it for 15 minutes, its started "bucking" like the OP said his car did under partial-throttle. I eneded up throwing a rod halfway home from the shop, so I'm hoping the blox will fix my issue before I chew up another motor.

If any of you are still having this problem and are running or have access to an ecu to datalog from, watch your o2/ wideband outputs as the "bucking" occurs. Try disabling the o2 input and take it for a spin. I've seen two different cars have this exact issue and both times it was actually a faulty o2 sensor believe it or not. the O2 is still giving a voltage reading so the CEL is not coming on, but the readings are out of the .1-1v range so the ecu is dumping fuel trying to get it within range and causing the extremely rich "bucking" symptom.

Try another o2 if you have one and just give it a shot and see.

bump from the dead, am having this problem when plugged in only when hids and heat is on if turned off and plugged in cars runs great

I think whatever distributor BLOX buys their TPS sensors from are Terrible. After reading this thread and seeing how similar my problem was to everyone else's, leads me to believe BLOX TPS sensors are faulty..

I have been running my for 2 yrs and have adjusted it many time to read .45 at closed throttle. The screws that came with them have been coming loose after a month or two being tight... I tighten the hell out of the screws everytime too. anyway after I adjust the TPS it will run good for a day and then the CEL pops up.

I found a used LS TPS from a good running LS motor with no CEL's and I have yet to change it but I think it will fix my problem as soon as its done...

After I saw the Bucking Bronco line I was like damn... I have been looking for a word to describe it and that was perfect... Everytime I get to cruise at 60 MPH the bucking and power loss follows...

I GOT SAME PROBLEM REPLACED THROTTLE BODY AND AND BOTH SENSORS STILL HAVING THE DAMN PROBLEM BUT I GOT A B18 IN MY CIVIC ITS WEIRD

does anyone know?????

Hello Peter, I've heard you've been having problems with your TPS reports...

I can't believe that in all this time nobody jumped on this.

hahahaha lol funny ****

Thanks to this thread i fix my car,had exactly the same problem with the blox tps,put a oem tps back and solved problem...blox=garbage
