Rx7 922

i have some fuel injector resistors on my car for the secondaries and i was wondering if they went bad would my car start to lean out? i have 550 cc primary and 720 cc secondaries. when i was in 5th gear and steppin on the gas and the rpm wasnt really moving, so i remember the store i bought them from said if the resistors go bad you car will lean out. im hoping thats the problem, is any one else using fuel injector resistors?

please help me out i need other opinions please
thanks

If you leaned out like that in 5th while flooring it, your motor would probably have popped. Do you have a boost gauge? If yes, how much boost were you making when you were flooring it and not going anywhere.

"when i was in 5th gear and steppin on the gas and the rpm wasnt really moving" How fast were you going and in what RPM?

i was going bout 60and it was about 3k rpm, it was boosting stock levels, but gears 1-4 were the same they were strong they werent weak like 5th. if the engine popped they wouldnt it effect all the gears?

does anyone else have any input please i need ur help

your not really going to go anywhere in 5th at 3k. 5th is an overdrive gear, its not meant to be used like 1-4 gear. its meant for highway cruising and better fuel economy

true but before i got more power out of it i mean when i gunned it the rpm was staying around 3k before it would go higher but now its just not moving like it used too

Read your secondaries out from the ECU (one at a time, of course)...Regular analog meter.

Go for a drive...

Watch them come on (voltage starts to drop from 14v or so)...

If the voltage is dropping, your circuit (which includes your resistors) is good...

Don't watch them so long that you're running into the guy in front of you...

right before my car started to run like this my engine light came on and so i turned off the car and started it again, then it was driving like **** in 5th, i know 5th is for better fuel but it also pulls too. this time it wasnt pullin at all.

also when i was looking at the a/f gauge it was reading lean and i run pretty rich.

so you guys think it is the resistors that are messed up?

Title edited to have a problem... please post real titles next time

so do you guys think its the resistors?

Rx7 922

well thanks for all the input.

Lol, what was the code for- the ECU puts these codes out to help us troubleshoot, find out which code it is...We can't magically guess what's wrong with your car...You've got to learn how to troubleshhot these things, or they will kick your ***...

No. But it would help if you tested them...

Rx7 922

ok well ill check it out and see wats up

i ran the test yesterday and i found out code 3 and 5 were stored in the ecu. i looked up the codes and tehy have to do with the fuel injection. so im thinking that it has to be the resistors.

HAILERS

Where did you get these resistors? And where did you install them? If the resistors were bad you'd have the problem in all gears, not just fifth. I'm predjudiced. I don't think the ECU has the smarts to detect anything other than if the injector wiring has an open b/t the power source for the injectors and the ECU pins.

So what I just suggested is to go to the resistors and make sure they are making a good circuit. In other words that they are not intermittently *OPEN*.

EDIT: NOT the resistors themselves but the connections at each end of each resistor.

i got the resistors at rx7.com and they were put on about a year ago when i had my engine rebuilt. thanks

Put in where? I soldered my resistors in at the ecu to avoid the heat and vibration in the engine bay.

Rx7 922

i put them in the engine bay, i think im gona do that next.

i ran the test and i came up with code 3 - crank angle and code 5 - knock sensor.

you probably have a faulty CAS or need to restab it. Just follow the troubleshootings procedures in the FSM.
