Fuel cuts , misfiring and more

[fastSRT4!!!]

Ok guys I hope ya doing good ,
I need some help and thous here ,
The car is spiking 18psi but holding 15
The problem is IF I do a dig or roll and powershift from 2nd to 3rd
The car will hit some serious fuelcut in 3rd , if I keep my foot on the gas
It will do it like 3 times on third gear and like 2 more on 4th then it'll stay at 110mph or so misfiring and not going forward , then when goin to neutro the car will turn off ... on the other hand IF I baby shift on 3rd and 4th it'll be fine , it does has the check engine on , p1187 and another one that ill post tomorrow morning , the spark plugs are 2 week olds , gap at 35 i believe , we check the sensor and they all have power , now according to some friends the problem might be
Stock fuel pump is bad
Coil pack
Spark plugs
02 sensor
Any help will be appreciate , and yes I had SEARCH a lot but nothing , thanks

I would check the spark plugs, wires and coil pack first.. Srt's do not have fuel cut, but they do have spark blow out.. Mods? If stock turbo I believe .050 is the stock recommended gap, so .035 might be a little but too much.. I'm pretty sure somebody will chime in to verify this information.. Also, p1187 is associated with overboost and map or tip sensor..

I will change the coil pack today and will check the spark plugs too , but .35 is wat I always use on my srt's and never had no problems

whoa .5 = half of inch
aslo .35 = ~ a third


but 0.050 is stock gap, and .035 is a great gap, you want the biggest gap possible with out blow out....

i run .035,,,


= )

if you run the 4306 u need to change them every other oil change...

your friend is prob right i had a local here and we swap everything and it ended up being his fuel pump..... i didnt have an extra to try.....

P 0108 , p0172 , p1187 are the codes that the car jus gave me

P0108-MAP SENSOR HIGH
When Monitored: Ignition on. TP sensor voltage less than 1.2 volts for greater than 1.7
seconds. Battery voltage greater than 10 volts
Set Condition: The MAP sensor signal voltage is greater than 4.92 volts for 1.7 seconds.
One trip Fault.
POSSIBLE CAUSES
MAP SENSOR VOLTAGE ABOVE 4.9 VOLTS
(K1) MAP SIGNAL CIRCUIT SHORTED TO (K7) 5 VOLT SUPPLY CIRCUIT
(K1) MAP SIGNAL CIRCUIT SHORTED TO BATTERY VOLTAGE
MAP SENSOR INTERNAL FAILURE
(K1) MAP SIGNAL CIRCUIT OPEN
(K4) SENSOR GROUND CIRCUIT OPEN


P0172-FUEL SYSTEM 1/1 RICH
When Monitored: With the engine running in closed loop mode, the ambient/battery
temperature above (-7°C)20°F and altitude below 8500 ft.
Set Condition: If the PCM multiplies short term compensation by long term adaptive as
well as a purge fuel multiplier and the result is below a certain value for 30 seconds over
two trips, a freeze frame is stored, the MIL illuminates and a trouble code is stored.
POSSIBLE CAUSES
GOOD TRIP EQUAL TO ZERO
O2 SENSOR HEATER OPERATION
O2 SENSOR
EVAP PURGE SOLENOID OPERATION
O2 SIGNAL CIRCUIT
O2 RETURN CIRCUIT
MAP SENSOR OPERATION
ECT SENSOR OPERATION
ENGINE MECHANICAL PROBLEM
FUEL FILTER/PRESSURE REGULATOR
PCM
TEST ACTION

code P1187 (Oil temp low volts

Code P1187 fix!!

It's all good, lol I wrote it at 5 in the morning so I was tired..

Great info brother , I really appreciate what u wrote but what should I do to fix the car , I mean I don't want to spend a heck lot of money and not find the problem , of ANYONE COULD BE MORE SPECIFIC PLEASE , NO1 here had this issue before ?

[fastSRT4!!!]

Ah btw the car is running rich , I can smell the gasoline when I'm on a stop and rev the rpms up
, I heard that If the car is running rich that might cause the 02 sensor read too much gasoline and send a message to the computer then the car would misfire ?
