Engine Performance problem
1986 Chrysler Le Baron 4 cyl Front Wheel Drive Automatic 89,000 miles
I have a 1986 Lebaron 4cyl. 2.5 TBI, automatic, with only 89,000 miles. Looks like new, and has been well maintained.
I have had the car for a year, and no one has been able to diagnose and repair the problem I have been
It has been to the Chrysler dealership 4 times, and all they can do is replace parts that do not even help the problem. Not to mention 2 other certified mechanics that have tested everything they can think of to no avail. So I thought I would give you guys a shot to see if maybe there is something that these guys have over-looked.
Initially the car got 29 miles to the gallon with the air on maximum, as the months have waned it has dropped to 22 or so, without the air on. All the mechanics have agreed it doesn't have a lot of power, but they can not pin-point the problem.
Car starts up every time, idles smoothly, no smoke.
It is throwing "no codes"! I check it everyday, just hoping it will pop something out, all I get is code 55 (end of codes).
Here is the list of all that is new.
(also had exhaust checked to make sure it had proper out-put, which it did)
TPS sensor and harness
O2 sensor and harness
Rotor and Dist. Cap
Things that were checked and considered normal:
Fuel Injector (TBI)
Exhaust back pressure
No leaks, no unusual smells.
Someone mentioned to me that the throttle body temperature sensor might be out of wack, but that would be a code 23, and I think is only used for hot re-starts, which it starts just fine.
I'm at a loss. Suggestions?
Thank you for your time!
have the same problem?
