do you have any type of fuel filter and do you have a boost referenced fuel pressure regultor because according to the duty cycle the injector are wide open

Thanks for the thought, yes, I do have a boost referenced fuel pressure regulator and the fuel pressure does indeed rise one to one with ...

Thanks Lance, I will give this a try tomorrow.

Wide band AFR creeps higher as RPM raises no matter what the VE is set to. Fuel pressure rises with boost. Engine is supercharged and logging boost shows a steady gain in pressure as expected. I have 96 pound injectos and max 8lbs boost. These injectors should be good to 900+ horsepower. I was ...

Sorry for the lack of follow up, especially to those that have followed up with me and the topic. I've been unable to get back to the car after making a handful of changes, but I'm convinced there were two problems 1. the throttle cable must have been binding at high load in 1st gear due to engine ...

Thaks for the additional replies.

I've added a 6 gauge ground from the body to the engine in addition to several smaller ones that already existed and the one from the battery. Since the most likely scenario seems to be a binding cable, I rerouted it slightly and to soften the bends that were there ...

Thank you for the follow ups. I appreciate the reponse. Sorry for the delay replying back.

Yes the throttle is sticking wide open and the TPS says it is open too. If you take a look at the snap of my log the TPS is 99 and doesn't release until the RPM is dropped below about 1500. The throttle ...

I've encountered a very odd problem. Driving along, depress throttle to the floor, engine reaches roughly 4000 RPM and suddenly goes flat as though the battery was unhooked. BUT, the throttle is stuck wide open and the engine continues to run as the car coasts with no throttle control. This happened ...
