Bogging at WOT, code 7, Quick fix? Or no?

Postby dexterthedeviant » Wed Feb 02, 2011 8:41 am

So I recently moved up to Nevada as some of you know, and when I got up here, I did a few things to the 88.
Changed the oil for something a little thinner cause of the cold, registered it, and did some cosmetic work. But recently I have been having an issue with the damn thing bogging when I cold start, when I floor it to get up some speed or even when I try to just accelerate a little bit faster than normal it tends to bog down. If I hold it there it gets worse until I release it. Now this goes on until I get it warmed up.
BUT tonight it kept doing it, and just before I got home it threw a CEL.
I flipped my nifty little switch I installed and it gave me a code 7. The TPS sensor.

Now correct my if I'm wrong, the TPS will determine how much fuel the ECU delivers to the injectors dependent on the position of the throttle correct? And if that is busted then I would be getting random readings and possibly an issue with bogging.

Also, living in a town that I dont have to smog, is there any benefit to clearing out my cat?

yes correct on your theory
if its bad or disfunctional
then you will be having a exsess amount of un atomized fuel ( air /fuel ratio)
or little beads of fuel in the head
partial air fuel mix starts the spark but since there is a surrplus of extra fuel it is causing difficulties
leading to a kinda of floodin effect

pull the plugs and give them a look over
there would be trace evidince of that at work
and if not a tps sensor is not that pricy

and the cat
if you clear the honey come you have a sleeper test pipe
less restrictions but looks 100% stock

might feel it and notice a 1-2 hp increase

Perfect, I will get right on ordering one of those.
I heard that Honda cats are made really well, but it is the stock cat... Maybe i shall just knock it out.
After reading a bit I see no harm in doing it.

Thanks toy chest.

Unfortunately it's welded in...
Demo and then vacuum haha.
I'll save that for when I have a full day off. Did you notice it getting louder?

yea but not a huge jump in decibles
noticible more in the mid range
where the back pressure used to stutter the flow of exahust
it will just be like a hearder with a resonated exaust

not going to make you a target for our friends in blue

This sounds like a good project. :)
I already have a resonator and a decent muffler as well.
Thanks bud.

Went from a dpfi, d series motor to a mpfi b16a VTEC and switched the wires... I know that I had to swap the wires for the dpfi to mpfi, but would I need to swap them back if I went to a b16?
I also swapped the ecu, OBD0 to OBD1...
Hmmm... I may try and swap those tomorrow.

unplug the connector and depin the 2 outside wires.
look carefully with a light and you can see a little spur (tab) holding the clip in the plastic connector.
I use a small prick pin. Maybe a screwdriver from an eyeglass kit will work too.
they slide in and snap back into place easily. ;)

Swapped those two wires, changed the oil, cleaned the air filter, added a breather filter, and test drove it...
I do believe that this worked, it will show in the days to come but it does indeed feel smoother and it accelerate smoother.
I'm pretty sure this was the issue.
I'll get back to you all in the next couple days.
