My Alfa 2004 computer box one of the pins is burnt what can I do?

if a pin is burnt on any ECU engine computer
inside a diode may have failed

ECU incl ignition key for Alfa Romeo 147 1 9 JTD 115 hp 5 doors 2004 Bosch...

find a used or referbished unit with same numbers on the outer casing as your damaged ECU
the replacement has to be from the same year and engine type as your car and same number of pins and plug ins

auto electrician might have the equipment and time to referb it

when fitting a used ECU
you may need to re sync the system with a diagnostic tool

I start my 2001 suzuki grand vitara xl7 2.7 v6 it runs fine for five to ten minutes and when i stop at a red light and the rpms drop down the motor stalls out but if or as long as i keep the rpms up i can...

can be lots of things, ill assume a hot engine at 180F ore more holding.
ill skip bad engines. (100ways)
1: EGR valve sticking open (very hard to reach in back)
2: ;idle speed control stuck. (clean both, and test both)
3;flooding, too much fuel, for many reasons. (takes tools)
4:air fuel mix , is too lean at idle. stalling,
5: dirty MAF, reads too low at idle. clean it with maf cleaner, from 6 to 12 inches away, do not blast it.with cleaner. gently.
6: intake air leaks, from Throttle body to head vavles, aka.
vacuum leaks, This engine is Air Density system.
if you have un-metered (maf) air leaks, it can go lean.

and never getting a tune up? last decade?. new spark plugs , new COP boots.
new air filter.
if super easy to correct with fast right foot , its not EGR main. leaking.
and if tuned up, i test the ISC valves. (IAC)

parts ?
page 42,. part #46 IAC (sticking)

page 2 part id. 'E"

(is check engine light on key? and goes out and stays out, running)
nomatter what scan the PCM for errors.? DTC errors.
i have the full 2 volume FSM on this car.(books)

FSM (factory service manual), one of the best made) SUZ.
FSM page 12b-24 EGR inspection and cleaning.
page 1C1 , how to service IAC

the throttle body has ISC valve on top of throttle , this open on a cold egine
if it fails, hot, the engine races fast . (opposite of your failure)
page 1D6 FSM

1: a full tuneup
2: clean ISC valve. totally. and put back.
3: clean MAF, (not map) the MAF is hidden in the TB and is no sold by suzuki, (shocker) so clean it with great respect. (using CRC maf cleaner. )
4: air leaks, causing lean at idle. (gaskets ,seals and vacuum hose leaks of any kind to the intake air PLENUM.

2009 mitsubishi lancer ex code p1238 & p1133 what does it mean? i take my car to get a general service change oil , air filter and transmission fluid... everything was perfectly fine till the next...

I guess my first question is did he clear the codes and did the check engine light come back on ?
The code 1238 is for a problem with the mass air flow meter which could be caused if the engine is running without an air filter in place.
I don't have any info on the other code.

1997 Mustang Cobra (4V, 4.6L), rough idling, won't stay running

It seems you have a problem with firing into combustion chamber,did you check if there is spark coming to all cylinders? It may also the coil pack that sits on the spark plug or the wiring to it ,whichever applicable.Be careful as this could cost a lot in terms of buying parts..hope this helps.
