Loosing power on hills/ no codes found


Recommended Posts

For starters...93 Loyal EA82 SPFI 104K. Last month the Roter and cap, plugs, and fuel filter were replaced, and the car tuned by the previous owner. Last week I replaced the battery.

 

The Problem: Car starts fine, seems to idle nicely at about 800

after it's warm. Seems to have plenty of power in first and second

and third at 3k to 4k. On the highway at 3K to 4 k in forth at 55mph or 2500 in fifth I start to feel the car studder or hesitate,

and when I come to a hill it seems to loose a lot of power, I'll be

in forth at 3500 doing 55 and it will slow down to 45 at wich time

I have to put it in third with the car feeling like it['s going to stall

out. I ran injector cleaner through it with a spendy tank of

hi octane chevron, didn't make any difference...

 

The check engine light will come on with the key turned to "on".

The only code flashing is six short flashes (Haynes says this

indicates MT California car).

 

So...any ideas? Can I check the distributer shaft with out taking it out? Anything else I should look for?

 

Thanks for your help in advance!

how many miles does it have on it you might be needing a new cat that why most of mine lost power the easy way to tell is go to your local lube place and buy a bottle of wynns v.i.c. fuel injection cleaner and run it through your pcv line with a funnel and hose this will clear your cat temporarly and give you some power back for a couple of months then it will go back to no power slowly

Chris, did you plug the "read memory" connectors together

before watching the 02 monitor for a code output?

Have you seen this site?

Your connectors will be by under the hood by the drives side hood hinge, the color may be white or brown, but not green.

Green ones need plugged together for setting the ignition timing

 

Haynes should stick to making underware IMHO

After figuring out how to retrieve the codes, this is what I ended up with....

 

#11: Crank angle sensor/circuit.

 

#32: Oxygen sensor.

 

For the crank angle sensor....Ok it's in the dizzy, and that is all the Haynes book would give me....said if it was broke, it had to be replaced...Anybody have any other ideas about trouble shooting the distributor. Also, will the same type of dizzy from

an 87 turbo work? (only cuz I happen to have one...).

Several years ago I owned an 80 ea71 wagon. it had a loose

distributor shaft that caused the same "hesitation/loss of power

at certian speeds/RPMs" feeling I'm getting from the Loyal. Me

thinks this might be the problem.

 

02 sensor: Is it worth trouble shooting, or should I just replace it?

 

Thanks again for everyones help,

Chris

Same thing happened to me 1 time, turned out the coil was bad, worked fine at a low idle or rpm, but when a load was put on it like a hill the coil would fail, hard to detect cause it's hard to work on your car when it's under a load..
