My first thought is a bad throttle position sensor (TPS). Check your service manual for procedures how to test it.

check engine light comes on? codes?

toyotanick

no check engine or codes. its very odd. it also isn't as obvious if i creep through it compared to if i get on the gas.

NytWolf

Instead of just posting to this thread, have you done any diagnosis?

dntsdad

I agree on the TPS. That would be my first test/swap to check.

could it be a bad MAF?

NytWolf

No...

recently brought truck to be tuned and even with a 14gph meth nozzle i am still a little lean up top so i am in search of supra injectors.

the question i have is fuel pump based. when i upgrade injectors to whatever they may be( i think i read 305cc supra injectors? i dont know what year etc yet though) will i need more fuel pump to push them? the swap truck is a 1994 toyota pickup with a 3.0.

the 7Mgte stock injectors are 440 .. I went with some RC 550 cc's for my 2WD swap , so I have some supra injectors for sale ..

hey guys, i have been having this problem for quite a while. my ac works great but my truck doesnt seem to know that the compressor is engaged so my idle drops ridiculously low. hamish_18 led me to notice that i have 2pins missing that are suppose to be there to tell the ecu that the a/c clutch is engaged. Not only have i forgotten what pins but i do not what i am suppose to bring to those pins?

Check the sticky thread, there's one I did for the A/C. There is no provision for A/C idle up in those wires you speak of. My idle dips for a split second, but always returns to 550-600. I've considered wiring in an idle up valve tied to the compressor clutch wire similar to the 3vze.

my cousins tacoma does idle down at all i dont believe...

Mine doesn't either. It is always 500-600 rpm no matter compressor on or off. Check how I laid out the wiring, and see if you have it wired that way. You shouldn't have any problems.
