I have a 1997 flhtcui after it warms up while at a stop light the check engine light comes on when you take off at the rpms reach about 2200 rpms it goes off until I have to stop or slow down has anyone else had this issue

 

Check to see if you have any codes:

I didn't know how to thanks for the info I will try that and let you know what I come up with

 

oil pressure red light? or is the light yellow?

 

The oil pressure drops when it does it but picks up and holds 20lbs while riding

 

sorry, was editing my post..oil pressure red light? or is the light yellow?

 

There is no oil light just check engine light

 

That will not work for the OP's bike. Those are the instructions for a Delphi EFI Harley. The OP's bike is a Magnetti Marelli EFI system. Here are the correct instructions for a 1997 Harley:

How To Determine Trouble Codes Stored By The ECM For EFI-Equipped FLTs *

(* Based on information gleaned from the 1998-2001 FLT Service Manuals **)

(** Special thanks to HogDoctor for supplying the information used in making this page)

Knowing which trouble codes are stored by your bike's ECM can greatly assist you in determining the source of a problem you are having. In order to check the codes on an EFI-equipped Electra Glide (FLHTC/U-I), Road Glide (FLTR-I) or Road King (FLHRC-I) without the benefit of a scanalyzer, do the following:

• Set the handlebar kill switch to 'on'
  
• Turn the key switch to 'IGNITION' for 3 seconds
  
• Turn the key switch back to 'OFF' for another 3 seconds
  
• Again turn the key switch to 'IGNITION' for 3 seconds
  
• Again turn the key switch back to 'OFF for another 3 seconds
  
• Now turn the key switch back to 'IGNITION' and wait.
  8 seconds after the last step, a sequence of flashing lights will begin (from the engine-check light). These let you read out the codes stored by the bike's ECM. Read the following to understand how to interpret the sequences:
  First the light will flash an 'intermission' sequence. This is a series of rapid flashes (3 per second) to tell you it is about to transmit a trouble code. The rapid flashing will then pause for 2 seconds. This tells you that it is about to parse out the first trouble code.
  The engine-check light will now flash at a rate of 1 beat/second to give you the first digit in the first trouble code the ECM has stored (just count the beats to get the number). It will then pause for 2 seconds and flash out the second digit at 1 beat/second and pause again for 2 seconds to tell you it is finished transmitting that digit (there are always 2 digits for a complete trouble code). Record these 2 digits so you can translate them, using the table below.
  It is possible that there is more than one trouble code stored by the ECM, so the rapid-flashing 'intermission' sequence will start again, followed once more by a 2 second pause to tell you it is going to parse out another code. Just keep reading the codes as described above until you get the same code fed back to you, because the whole cycle will keep repeating once the last code is flashed out.
  To interpret the code (or codes) you have read out, refer to the chart presented below:
  
  Trouble Code
  Description of Fault
  11
  Throttle Position Sensor
  12
  Barometric Pressure Sensor
  14
  Engine Temperature Sensor
  15
  Intake Air Temperature Sensor
  16
  Battery Positive Voltage
  23
  Front Injector
  24
  Front Ignition Coil
  25
  Rear Ignition Coil
  32
  Rear Injector
  33
  Fuel Pump Relay
  52
  ECM RAM Error *
  53
  ECM ROM Error *
  54
  EEPROM Error *
  55
  Microprocessor Malfunction *
  56
  Crank Position Sensor/Cam Position Sensor Signal Error **
  
  * - Requires ECM Replacement
  
  ** - Not applicable for 2001 Models
  
  

 

How things have changed

Glad you saw my mistake, now maybe he'll be able to check the codes.
Thanks
