s14 throttle issues

[faqz09]

I have 96 s14 that I just purchased. Im not familiar with nissans yet so bare with me. It is a ka24de, it does have a slight tic noise that dissappears when u rev anything higher then idle. The problem is if I hit it while the car is cold it will rev all the way up the FIRST time...any other time after that it boggs down at like 2.5 or 3 rpms. I had an integra that wouldnt rev past 2000 rpm and it ended up being the distributor, could the be the case? what should I look and check for....recently changed the knock senor....car not registered so I cant get it scanned

What do you mean by car not registered so you cant get it scanned? Are you throwing a CEL? Borrow a computer from a friend or autozone and check for codes.

[faqz09]

I ended up sayin F it and went to autozone...s*** load of codes...p0180 p0446 p0130 p0135 p0100 p0325...and it gave knock senor and I changed it

[alms24sebring]

What are the codes? I dont know those numbers by heart. One can throw another.

[Jmoore124]

Yeah google them and your make/model and it will usually come up with ideas and culprits etc. Like ALMS said, many times with that many codes at least a couple will be linked together. At least you have a starting point now.

well few are kind of similar but I still dont know where to start p0130 front h02s p0135 front h02 heater P0100 MAF sensor(im lookin up how to test it now) P0325 knock sensor(even after replacement) p0180 fuel tank temp p0446 vent control valve....im starting with the MAF sensor but after that im lost...can anyone tell me all the proper ground locations so I can make sure they are good also

[faqz09]

White wire was 1.4 idle but only 2.6 at 4k, i think this is because I got like 44ohms of resistance on the black wire smfh. power supply was good...my question is where should I look for now? where are the grounds for this circuit and could it be my low reference(ecu) ground???
