im gonna check that next,id hope not bein the fuel pump is a few weeks old

I was thinkn how does the 7mgte ecu know if your in boost or not?All other turbo cars ive owned had a boost sensor that sent a signal to the ecu but my 7mgte does not,is this right?misses and bogs out during boost and at low rpm/speeds it cuts out momentarly while driving somtimes.Ifi was to...

I fixed the iscv check valve but still no dice,runs lean and misfires during boost.I swapped the fpr that made no difference either.also another problem i noticed is that somtimes the idle lopes if i am to hold the engine at 1500 rpm in netral.I havnt managed to rent a fuel pressure gauge yet...

danm im missing that part could be some of the issue.Now i bet finding that part is gonna be trouble.

can u visually see the check valve in the manifold when the iscv is removed?i dont recall seeing one.Im gonna try and replace the fpr cause i got a couple spares and i think its possible that mine is bad it will run lean before boost somtimes as well.kinda does act like its running out of fuel.

i know the fuel filters are clean,im running a hi flow carter fuel pump that out flows the walbro.My base timing is set at 12 btdc.Im certain that i have no vaccum leaks. the hose that runs from the intake to the iscv,should that have a check valve in it?

wideband o2 and digital gauge plx300

No boost leaks for sure i found two couplers that had tried to come off so i double clamped every thing and tested it.The trouble is im running lean and not sure why.It may be that my fpr is the na one but i havnt been able to find a post related to a difference between na and turbo fpr.

does the ecu only require a switched power supply or does it need constant power even when the car is off?the wire diagrams i have do not state wether its needs to be switched power or not.

thanks for the link now i just gotta figure out how to hook up the check engine light.Gonna be interesting cause my car was originaly a 4cly 22r carburated.

im running gte injectors afm and ecu,the black injectors are 440's right?im running the later style electronics with the grey plug harness and ecu,how do you go about getting the codes from the ecu,is there a code reader available?

ill chech for boost leaks tonite.where should the afrs be at during boost?and my engine does have na pistons and cam it was just rebuilt a couple weeks ago.Would the na pistons also be part of the problem with the lean conditoin?Is there any difference between the na fuel pressure regulator an...

I recently swaped a 7mgte into my mk3 celica and while under boost at anymore than half throttle it stops making power and sounds as if its misfireing or running out of fuel although the afrs are between 14.50 15.00 during boost.Any one have any ideas what it may be?

I have a 89 7mgte that im swaping into my 82 celica and im using the grey plug harness and ecu.I ran into a problem with the cps i bought, the plug is a different shape and has different color wires .Please help i want to have it running by saturday so i can show the beast at a car meet sunday...

well ive done a lot of searching and i have came across the acis but did not know what it was until now,and it seems that kepping the acis is a much better idea,it exsplainsthe cars powerband when i drove it home,far as the egr removal i have a jdm ecu,and the pcv valve to the exhaust sounds...

must have been,but i will be running no cat and no emissons stuff and the only vaccum lines i plan to run is brake booster and the iscv,which brings me to another question,the cold start injector has a vacum line directly under it seem like it controls a valve or somthing,can i route that line...

well im rebuilding a 7mge to go into my celica gt,and i was going to pull all the emissons stuff off ,to many vaccum lines and i dont like oil and carbon making my intake plenum all dirty,any how is it gonna cause any running issues,i noticed there was a sensor that pluged into the egr.i have...

yea i a disease call mss,mutiple supra syndrome:sarcasm:

ive been int supras for 5 years now and will soon own my first mk3,ive been building the mk2 with engine swaps,and full suspension mods for a while,but i like the look of the mk3 so i figured i should drive one of them too.my goal is to own a supra of every model mk1-mkiv,right now i curently...
