87 Reliant, power loss and stalls. Got codes but dunno what.
 

Hi. My 87 Reliant (2.5L) stalls when stopping, especially when colder.
Hesitates when running, and has low power and bad mileage. I got codes
33 and 34. As per a list of codes, they refer to AC and speed control,
but my car doesn't have AC not cruise. Anyboody knows of alternative
interpretations that may give me clues? Speed sensor maybe?

Thanks a lot

Hi streblo...

Not a mechanic, so I stand ready to be corrected, but I think
you'll find that "speed control" doesn't refer to cruise control,
but rather to the speed sensor...

I further suggest that it's in the transaxle, and is responsible
for "deciding" whether the car is idling or coasting, and the
computer uses that information to determine where to put the idle
air control motor.

Take care.

Ken

Code 34=Speed control solenoid circuit driver. This code will be set if
vehicle does not have cruise. 33 will also be set if no A/C.

Vehicle speed sensor would be code 15.

So Mike, this means that 34 and 33 will be set as default codes in my
cruise-less and AC-less car? in other words, I'm getting no fault codes
in spite of the evident failures. Any ideas on where to loook first?

Yes. I don't know why chrysler did it that way but if you don't have cruise
or A/C, those fault codes with be set.

Don't know how many miles you have on that but a compression test might be
a good place to start. Then I would check the usual, plugs, wires, cap,
rotor. You didn't mention if you have a carb or fuel injection. If it's
carbureted it might be time for an overhaul or replacement. If it's fuel
injected check the idle speed motor. You might also want to hook up a scan
tool that can read sensor data while on a road test to see if you have a
sensor that is out of spec, but not out enough to set a code. A bad O2
sensor or MAP sensor may cause those symptoms.

I would look for vacuum leaks and do a basic tune up. The other possibility
but a long shot would be the torque converter lockup isn't coming unlocked,
but look to the easy stuff 1st.

Hi, I have an 88 reliant and I am almost experiencing what you are going
thru. My 2.5 liter 4 cyclinder has about 300 000 plus kilometers on it,
and I do have aslight power problem with starting and idoling. it tends to
want to stall and idol very roughly, even though its fuel injected,
something is not right... Ii replaced all spark plugs wires cap and rotor
and yet its been almost a year since I replaced it entirely, it still runs
roughly in both warm and cold temps. I think my problem may be coolant
related. have a leaky radiator and leak about 2 liters of water every 2nd
day i have to refill it, that is when it really loses power and becomes
sluggish in acceleration when water is low. Not sure if this is of any
help to you so thought i may run this issue by you.

If the car will not start with the map sensor connected and will when it is
disconnected you found your problem!!! replace the map sensor because it is
shorted out.
