Hi all, I'm new here.
I own a 86 Chevy Caprice that is my every day driver. It has a 305. My driveability issue is that of the carb (Rochester quadrajet). It all started when I removed the computer sensor (ecu?) on the top/front of carb. I did so cause it was causing it to have hard starting/hesitation problems. This cured it for a few months until about a week ago.
Now its even worse as I have a very rough idle, hesitation, bogging out taking off from idle and 2500 rpm plus, and repeated stalling. I can only go about 25 mph before it starts badly bogging out and then stall out. I've put it in neutral and revved it up to try to clear the carb out, but didn't help. It acts like its loading up (dumping too much fuel in).
I've came down to that I need to replace the carb, but need to stick with a similar cfm as stock. What is the cfm on a Rochester q-jet. stock for this car?
I'm thinking of an edelbrock carb for their reliability (daily driver here). Any other recommendations?
Also, this smog pump has been driving me nuts anytime I look at it. I think it also may be tied into my issues as explained above. Good or bad idea to remove it all and process involved please?
Thank you,
Jackie.
