So yeah I had a code for a TPS so I ended up ordering one from BLOX. Shortly after the install I figured everything would be fine. No check engine light, good idle. Well I went to punch it after the motor warmed up and it's still bogging in the 3800 to 5700 range. It hit vtec a couple times and then quit working again.

I am now resorting to buying a IACV and a MAP sensor but I'd hate to waste money with buying both. Does anyone have any solutions? Car still smokes a little bit up top but most of the time I'm limited to driving under 4k to keep the engine from breaking up. Then I ran into an idle issue, I clutched it coming off the ramp from the interstate and the car died but quickly fired it back up. A little down the road I pulled over to recalibrate the TPS and the car started reving up and down just a little (500-800rpm). It later quit, but I still can't floor my car through the band without any hesitations. Any help?

 

testing the voltage on the tps right now... it looks to be reading good. any help?

 

Maybe try a fuel pump?? I had a coupe with a single in it did the same thing idle great but hesitated really bad right after 3k replaced the pump and all was good!

 

hmm...

 

actually i think thats what it is... the car sat for a year.

 

it's not the fuel pump... i force shifted into the vtec band (2nd gear), it will hit vtec every time doing that but at about the end of the 3rd gear around 7600rpm it will cut 100% fuel leaving me with the open throttle body sound (really loud) and will immediately throw a code: tps and knock sensor (even though I just changed the tps)

 

This may not be worth anything, but since the car sat for a year try changing the fuel filter. Technically if the filter is clogging up you should get bogging all over the power band, but its cheap and worth a try. Just my 2 cents.

 

Thats the first thing we changed.
