unplug tps and it doesn't bog. 95 integra GSR with b18a1 swap. Really healthy.

New spark plug wire, spark plugs, fuel filter, head gasket, intake manifold gasket, tps sensor, tried running 91 octane, clean the iacv, and hooked up the fitv becuase it was bypassed prior.

It'll bog on partial throttle after it warms up, sometimes when its cold too. But more often after it warms up.(with tps connected)

The Distributor looks pretty new. the rotor looks find, as well as the contacts on the cap.

I tried two different ecu's, an obd1 pr4 and obd1 p75, bogs with both.

With the tps on, it'll sometimes idle like it has a dead cylinder, but without the tps on it'll idle perfect.

I really need to fix this problem because it is bothering the fudge out of me.

edit: it threw a fuel supply code at one point, with the p75 ecu, never with the pr4.

Ignition timing and timing belt has been checked.

 

Tps sensor voltage is off.
Was it replace? If so test the volts on it.
Turn key on, but don't start.
Than check voltage by using a multimeter.
Point positive end to the tps and the other on frame.
Don't press on gas pedal on the first test. It should be at 0 volts, if not adjust it until it reads 0.
Try it now with gas pedal to the floor.
Should now read 4.5-5 volts.

Need two people or just do it by flipping the throttle body for WOT.

 

any other problems? an uncalibrated tps shouldn't cause it to miss when its idling. I'll check it tmrw morning.

 

It shouldn't, but you said that the problem was your tps sensor so I'll try that first.
Good luck.

 

oh yeah, id like to add that at one point, it actually threw a fuel supply code, forgot the exact number but it was fuel supply.

 

So u put an ls motor into a gsr?

 

yea? you said you "tried 91 octane", but a gsr should be running premium gas all the time. i think that ranges from 89-94 depending on your location.

 

I bought the gsr shell and threw an ls in there to get it running.

The octane level is dependant on the motor, not the car. Since the motor is an LS, I will use gas that is appropriate for the engine.

I also checked ignition timing and timing belt, dead on.

 

check to see if your fuel pump is priming.

 

o2 sensor, end of story. pm me if you have a problem similar to this and i can help you out.

 

Good to hear! And thanks for actually posting the solution to your problem, instead of peeps who just ask questions an dont bother posting what the fix was. It really helps people who search for a problem like this.
