Guys I have a 92 Custom Cruiser that appears to have gone into "limp Home Mode" How do I clear that and keep it from happening again
Sorry but as an old coot I have not kept up with these newfangled contraptions. However I went back to your WLECOME and am now both happy and sad. Two of our favorite members were there to great and tease you. They have since gone to that great station wagon garage in the sky. Also we were in the middle of a discussion that never got an answer. Just what is a female old coot called. If you find time between your repair work please see if you can come up with an answer since it's your fault this even came up.
Does it have any trouble codes? Can be a solenoid, problem with valve body or even something as simple as a ground issue or bad transmission. Google "fail safe" or "limp home" mode and what trans you have (I am assuming 700R4) and you may find some helpful diag test you could perform to help get you going in right direction. Good luck and keep us posted what you find out. I will look around on the web and if I see anything that may be helpful I will post a link.
Wait...is it the engine or the trans that went into 'limp home?' On some vehicles (like the Chrysler minivans), limp-home works on the ECU for both engine and electronic trans problems. So you need to scan the computer (a wire jumper in pins A and B of the DLC will make the CEL flash on the instrument cluster) and Google the code as it pertains to your Custom Cruiser and the engine/trans it has.
The 1992 OCC does not have a computer operated transmission. Just s single solenoid for the torque converter clutch. What exactly are the symptoms you are experiencing?
A TBI Chevy 305. In any case, 1992 is still OBD I. You clear the computer by disconnecting the battery for about a minute, as this simplistic computer doesn't have non-volatile storage. To keep it from happening again, you need to diagnose the problem that caused it and fix it correctly. Is the Check Engine light on? If so, there is a stored trouble code or codes in the computer and you should definitely read out what it is before clearing it. If the check engine light isn't on, then the problem is not with the computer controlled systems. What exactly is happening that makes you think it is in "limp home mode"? As I noted, the early TBI motors have limited computing power and limited ability to go into a "limp home mode".
Olds Custom Cruiser Sorry Guys and Gals I've been away from my computer for a couple days. The trans is a 700R4, non computer controlled, and in 92 you could get the 305 or the TBI 350, mine is the 350. The cat was plugged so I did a hillbilly delete, cleaned it out completely, and on the test drive it started losing power and about 25 mph was all it would pull on the hiway. It does have a check engine light and I don't have an OBD1 scanner so I'll have to come up with one or figure out the blinking light system. I'll read the rest of the posts and see if I need to add anything more. Thanks for the prompt replies, I'll get back to you all later.
Female Coot By the way CatModelT I'm assuming the a female Coot is like a Count and a Countess, therefore Cootess
I have a paper in my glovebox with the codes on it, I had the problem of the converter getting plugged on my Roadmaster but it was because it was running too rich and melted the converter. If it is running too rich and that is what's making it lose power, the advice I got from here was check that ground that goes to thermostat housing for corrosion. If not grounded properly it could cause it to be dumping more fuel than it can handle. In my case I think the code was 15 can't remember but it was cooling temp sensor telling computer car was cold. Car ran great at initial start up but 5 or 6 miles it was loading up so bad it would't hardly run. If you count the flashes and post the code I am sure someone will tell you what it is. If no one post it before I get home, I will look it up on the paper I have and post it.
One of the most common problems that causes the cat to clog is the O2 sensors get dirty so misread. No codes come up because the sensors are working electrically. Bad O2 sensors can also make a 30% difference in gas mileage if the experts are to be believed.
OCC limp home mode Drove the OCC this morning, cel was gone and it ran fine, but didn't drive it far so I'm guessing that after 5-6 miles it would come back. Will keep y'all posted. Thanks
