Re: 91 camaro 305 tbi running rich

I've had a false ECT reading cause this more than once on my car. A bad connection at the sensor made the ECM think the motor was at below freezing temperatures. Although, ambient temp was closer to...

Re: 305 TBI, won't idle and surges when runs

I'll backup the fuel pressure check idea. Could be a slit or hole in the short rubber hose that connects the fuel pump to the hanger assembly. Also, if you've solved the stumble issue yet still have...

I had two different issues that caused my car to just shut off then start back up with no sign of problems. One was the VSS. It would "glitch" when moving from a stop. The speed being reported to the...

tooltime,

So now it stays running but rough? Does it still backfire through the tbi? Backfiring is a sure sign of something out of order in the ignition.

Did you try shorting the ALDL...

From your first post, you make it sound like lack of fuel. "no joy on keeping it running without spraying the crap out of it." Although, you seem confident that the fuel system is working. "New pump...

Re: Camaro iroc 305 TBI high idle!

2000 rpm idle is most likely a vacuum leak.

Like ex-x-fire said..tbi base gasket. The material gets dry and brittle over the years. It's easy to pull off the tbi unit, so I would do it anyways....

Re: Is this common for a 305????

I've got a 3.73 posi in my mostly stock 305 tbi. I'm lucky if I get a quick chirp off the line. Although, my rubber is fairly fresh. Only a few months old.

Since it's been converted to carb, how is the AIR injection valve or EGR valve even being activated? These are/were both controlled by the fuel injection ECM. Also, the carb could be out of tune and...
