It's completely random and has happened about 4-5 times already. It only happens when I'm WOT and shifting near redline, but right when I shift the car throws a CEL and has no pedal response. The rpms just begin slowly dropping and if I try to step on the gas, nothing happens or it barely responds. The only way to fix the problem is to flip the key real quick (turn the car off and on) and everything is fine.

I never had a chance to check the CEL since I'm usually in the middle of the road. I'm about to take the car to the track and I would really hate for this to happen on the track. Any ideas what it might be?

I'm running a built B16A with a Drag3 kit. Boosting about 13psi. Running Uberdata.

Thanks.

 

Bump

 

Are you running a check valve? That sounds like a MAP problem.

 

He said hes running Uberdata so no check valves.

When you get the CEL, just pull over and jump the service connector to check the code. Its no point wasting time and effort trying to guess what the issue is when the CEL will help in indicating where the fault is.

 

Well it happened again today. I pulled over to a gas station and checked it. Was code 16.

I think the car went into a limp mode as well. Redline when that CEL came on was at 3500.

*shrug* no idea what it could be... injectors are all plugged up properly (rc 550's).

 

Bump.

 

are you running ftl by any chance?

 

Did you have to install injector clips? If so, one of the connections may be loose.

Nah, not running FTL.

Do you mean the metal clips? If so, yeah (don't you need them regardless?). All the injector connections seem to be fine. I tried wiggling and slightly tugging them when the car is idling and they all seem fine.

I'm wondering if it's something to do with my B&M FPR or fuel pump (Walbro or BBK).

 

The ecu is complaining about your injectors

 

What kind of connections did you use? If you used butt splices, that may be your problem.

I'm not quite sure what you mean? I am running a OBD1 GSR harness. The wiring harness and injectors plugged right up.

I wonder if it's something to do with Uberdata. I don't know of anyone else having the problem though, and they're running UD as well. *shrug*

 

Im having the same problem. I get on it and after i let off the cel comes on throwing a code 43 fuel system failure. I have lucas 440 injectors with the safc. Im stumpped too. Also when i drive and go to about 4000rpm and then let the engine slow itself down right when it gets to 2000rpm the cel comes on throwing the car into limp mode giving me a code 43.

 

Check your thermostat ground.

 

for that code 43 . . . I use to get that a lot. Actually took my car into a shop because I couldn't figure out some other issues with my car after messing with it for a couple weeks. I have not had a code 43 for months, but they said the car tossed a code 43 for them and they found that my stock FPR was stuck closed so my motor was getting way to much fuel, so they replaced it.

Try checking your FPR
