correct me if im wrong but dont you need some sort of fuel management to succesfully run the lex/550s or 560s?

Read my thread...title is : Question about fuel system and tps I have learned what causes 51 and how to diagnose Sent from my PC36100 using Tapatalk

Also test your tps 1st to see if it needs adjusted If your tps screws are anything like mine then they're a PITA and just want to strip lol I have another tps ill test tomorrow Take a video of your car hiccup during idle and ill see if mine is the same Sent from my PC36100 using Tapatalk

In jetjocks calibration thread... Says to jumper E2 and IDL on tps plug Check codes If 51 is gone then wiring is good for E2 and IDL did just as he said Code went away So since my resistance on IDL pin is reading infinite resistance my tps is bad Reading should be under 2k ohms As far...

Ok so I got some good clarification of what my code 51 issue is Dan what happened with your tps was your IDL pin was shorted and sending a constant voltage to TCCS telling it the throttle body is close While VTA pin was sending voltage to TCCS telling it the throttle body is open When VTA...

^^well are cars must be sickness twins lol mine does almost the same thing at idle a pop/miss will be heard once or twice every few seconds but i think my problem is due to the following...possible bad tps, cracked cps cover and my iscv will act up from time to time lol it was weird though...

for a home made boost leak test i took a piece of 2.5" exhaust piping...cut a section off(about 4inches) took a flat piece of sheetmetal welded sheetmetal to 1 of the openings cut sheetmetal down(just for looks lol) drill a hole big enough for a tire valve stem to barely fit pull stem...

My car revs fine and have never had a problem with revving I suspect tps is bad so ill order a new 1 after I do a little more diagnosis

After finding which cylinder is giving you problems Double check you plug wires are in the right order Check for spark at spark plug side of wire If ignition source is good Grab a multimeter Check injector connector pin for voltage 1 wire should have a constant 12volt with ignition switch...

Thanks for the info So if I'm thinking correctly If there is no resistance at E2 then my car shouldn't rev past 1800rpm...correct? Sent from my PC36100 using Tapatalk

Start it up Pull a spark plug wire If another miss occurs reinstall wire and move to the next until no difference in engine sound is heard That will tell you which cylinder is misfiring Sent from my PC36100 using Tapatalk

You will lean out and eventually kill the motor There's another thread where I guy found out he has a Lexus AFM with stock injectors Runs like Shit Sent from my PC36100 using Tapatalk
