Actually, I just did. Its gone on its way to the Albany area now. It was sold to someone who appreciated the car. I anticipate it will do very well with its new owner.
Now I am looking for a car to work on...I have a dual quad Buick 430 and a Buick 455 4 barrel on stands in the garage. I...
I've found a hypertech chip for the car. Should be a little improvement.
Although we just got snow so the roads are all salted again.....
Hopefully it will rain soon
Lol you guys are hard to please!
Looks like a good start on a 84 hurst olds project to me! These dont grow on trees, and I've seen plenty waaaaay worse. I'm not from California or AZ
So after a winter spent leaking a river of fluids on my garage floor, the Hurst it back in action.
I found the trans leak at the lockup electrical connector o-ring. Fixed.
Power steering gear was leaking at the input seal. Pulled it apart for a full reseal job, and its dry as a bone now...
I am only finding the headlamp switch w/o interior dimmer new. Only finding the combo switch used on ebay.
I will take a look at it today. Maybe I can find a fix. The problem likely is the foil circuit.
When the rheostat for the gage dimmer is all the way off, the lights work right.
If I use the gage illumination the hi beam indicator turns on for low beams and off for hi beams. Also a turn signal indicator lamp stays on.
Might be a foil circuit problem? Gages all work correctly.
Thanks for the Distributor wrench trick guys. I used a 1" open end wrench on the distributor "square", and with a little persuasion via hammer, it finally broke free and rotated.
With the test terminal grounded at the ALDL, I set base timing at about 20-24 degrees. It was flopping around a...
I credit 307 403 with the suggestion that got me moving in the right direction.
The hardest part was relearning the CCC system and triple checking it's functions. Trying to diagnose the exact cause.
The Fbody site was just corroboration. And part numbers.
It seems so obvious in hindsight...
Installed an AC 213-632 today. Problem solved.
I now achieve closed loop function that responds via dwell to idle mixture changes at the carb.
The car is running, and smells, a lot better!
Thanks for all the help!
I found a deal on AMAZON. got an AC Delco 213-3076 heated sensor for $14! its on the way and Ill give it a try at that price.
EDIT:
….and i see that 213-3076 is a WIDEBAND AFR four wire setup that I believe inverts the output. In our cars with a full rich command - low dwell - we should...
yes they are one wire, but no the sensor circuit does not ground at the exhaust. That would be a short circuit and would omit the ECM. I was referring to checking the ECM O2 sensor circuit ground.
voltage generated by the O2 sensor runs through the purple wire to the ECM, then back out the...
yes I have put the engine on the fast idle cam 2500-3000rpm and watched dwell while I choked the carb and made vacuum leaks. no changes in dwell.
The only time the dwell seems to change is as follows:
cold start ~32dwell seems to change to 40 or so once the engine heats up a bit. It does not...
yes headers. I took a look in the pipe and the o2 sensor is not obstructed at all. It is very much in the exhaust stream. About an inch or two back from the collecter flange
its perplexing. All of the sensors check out good. TPS, temperature, and o2. No codes are set. System appears to be...
The thing here is, the dwell isn't varying like closed loop should. It sticks at a value like it's in open loop.
The dwell when hot does not respond to changes at the idle air bleed or mixture screws. Does not react to manually closing the choke flap.
This tells me it's likely in open loop...
Its as if the sensor is not sending enough voltage and the system is not going into closed loop function as a result.
I checked the bung installation. It is an inch or two rearward of the header collecter, in the head of the exhaust pipe. I looked into the pipe and the sensor is not at all...
