    ok thanks, you pretty certain of this? and how easy would it be to repair or change this? And also if this is the problem, would it restore the power and acceleration at full throttle or any throttle position for that matter?

Repair or, replace the MAP flap switch on your engine's intake tube this switch measures the air volume admitted into the engine so that the engine computer can adjust timing and, fuel injector speed.

Possible causes of 3,400 to 4,000 rpm engine cut-out


The speed buffer is bad. Older cars had these buffer modules out side the engine control module(ECM) Pre 90's. Newer cars have them built into the ECM. The buffer digitizes the analog signal sent from the speed sensor. This is the reason your car cuts out at 4000 rpm's. It's not recieving a signal from the speed sensor and thinks it's still in park.

My mitsubishi eclipse 95 gs wont start and theres no light on my dash bored it will cranck but wont start at all i need help asap


Since the engine cranks, the battery, starter motor/starter motor solenoid are most likely
good, so suspect everything else on the list. When you narrow it down, re-post with a
more specific question about that particular component, since 100s of components must operate
nearly perfectly for a vehicle to actually start.

1 Inspect Battery -- Battery Discharged or Faulty.
2 Inspect Battery Cable -- Corroded, Broken, Shorted or Poorly Connected Battery Cable.
3 Inspect Battery Cable Connector -- Broken/Corroded/Loose.
4 Inspect Fuel Filter -- Clogged or Dirty Fuel Filter.
5 Inspect Ignition Coil -- Faulty Ignition Coil.
6 Inspect Wireset (aka Spark Plug Wires) -- Worn, Damaged or Faulty Spark Plug Wire(s).
7 Inspect Spark Plug -- Incorrectly Gapped or Fouled Spark Plug(s).
8 Inspect Starter -- Starter Motor Faulty.
9 Inspect Fuel Pump -- Low Fuel Pressure.
10 Inspect Solenoid Switch -- Faulty Starter Solenoid Switch.
11 Inspect Fuel Pump Relay -- Faulty Fuel Pump Relay.
12 Inspect Fuel Injector Pressure Regulator -- Faulty Fuel Injector Pressure Regulator.
13 Inspect Ignition Switch -- Improperly Connected or Faulty Ignition Switch.
14 Inspect Starter Drive -- Faulty Starter Drive.
15 Inspect Fuel Injectors -- Dirty or Worn Fuel Injectors.

Looses Power at high RPM's


Hello! A cylinder misfire can be something as trivial as needing new spark plug wires, to having a dangerous lean condition in the fuel mixture. Assuming that you have a stock, un-modified car, with a stock, un-modified PCM, my suggestion would be to swap the coil packs, to isolate whether or not the 1 - 4 coil pack is faulty.


Hope this helps, and thanks for using FixYa!

Engine cut out at 4500 to 5500 rpm while you are driving.


Check your fuel pressure, and see if your exhaust is flowing right. If exhaust is not flowing good then your catalytic converter is stopping up. Low fuel pressure would be because eather fuel filter, or fuel pump. Also check your air intake filter and your fuel ratio.

Car starts and idols fine but once you get it to 4000 rpm it cuts out and then every time you hit the gas it will accelerate then cut out. it doesn't die out until you do this for a long time.


Ya know First i never drive a car at 4ooo RPMS cant remember when but anyway.
Check the Intake Air tube the goes into the air cleaner and throttle body for cracks and cuts and being loose. Fuel Pressure have it checked while you are driving to make sure your noy loosing fuel pressure at the high Rs. Ignition System Factory Plugs and wires no fancy discount suppose to increase horsepower stuff
