I own a 99 cougar and I'm having problems with it, can someone help me?

Question

i got a check engine light, and here is what i got:

P0708 Trans Range Sensor Circuit High Input

P1744 TCC System Performance

P0420 CAT Effic Below Threshold (Bank 1)

P1519 IMRC Malfunction (Intake Manifold Runner Control)

When i start driving, there's no problem, works just fine when cold, but when the temperature raises to normal, it will start to shake, pull and its kinda jumpy around, specially on the highway anywhere from30-50 mph

Answer 1

P0708 could be caused by a bad P-N-D sensor (or range sensor) or faulty wiring.
P1744 is the torque converter clutch. Could be dirty Trans oil, defective solenoid or other horrible things inside the transmission.
P0420 indicates the PCM is not receiving the right signal from the oxygen sensor (Bank 1, Sensor ?) or a defective catalytic converter.
P1519 is a module to control intake air from a low engine speed to a higher one.
Ignore P0420 and deal with the others first. There more apt to affect engine performance and power transfer.

Answer 2

The last three are the only ones you want to focus on...the tranny code is because the engine is missing when it gets to normal operating temperature. Sounds like you have a bad coil on the high energy ignition system. When it's warmed up and sitting if running rough, spray starter fluid into the intake. If it smooths out, then you have a fuel problem and you need to troubleshoot the fuel system....if the car continues to run like crap, then you need to find out which cylinder is missing and replace the respective pickup coil, plug wire, or plug. Good luck.

I can't tell you for sure without actually doing diagnostics on the vehicle.It's the same as someone who calls the shop and tries to explain a noise.It can't be done over the phone!! Or over the computer for that matter.IT is possible that P 1519,o420,and 1744 are related.Fixing one MIGHT cure the others.A diagnostic computer in the shop would give you a "fix first" listing.So,you need to find a reputable shop to do this work for you.In our shop,if the repair work is done there, you get a break on the diagnostics charge.Call around and ask.Get it done right the first time and get a guarantee!!

Answer 4

Electronic ignition, Elecrtonic trans control, Electronic fuel injection, Electronic everything.
Take it to a shop.
