yo,

What year?

Have you pulled Codes yet? KOEO for now

a Self Test for Diagnostic Trouble Codes (DTC)s by my pal, BroncoJoe19 @ http://broncozone.com/topic/14269-code-reader/page__pid__74587__mode__threaded

Next would be to do the simple FI Test shown below and then fuel pressure test

If it is 92-96 then look at Tan wire that is common to all injectors an travels back to EEC

if a 90 and some prior years; it is Tan/Orange and goes to EEC pin 58 or 59 depening on injector number;

89 is Tan/Orange and Tan/Red

ISSUE: Port fuel injected vehicles that have cold hesitation, lack of power, rough engine idle or a surging condition at steady speeds may be caused by dirty fuel injectors. When no-detergent fuel is used, deposits form on the fuel metering surfaces of the fuel injectors. The deposits that form reduce the fuel flow resulting in a lean condition.

ACTION: To correct this, follow normal diagnostics as shown in the Engine/Emissions Diagnosis Manual, Section 2. If you get to a step that instructs you to replace a fuel injector, FIRST try cleaning the injector with the Rotunda Tester/Cleaner, 113-00001. If the condition still exists after cleaning, the injectors should be flow tested to make sure they are functioning properly. If the flow test indicates lean injectors, a second cleaning may be necessary because of severe injector fouling. Refer to the diagnostic chart for step-by-step instructions.

CAUTION: NEVER ATTEMPT TO FLOW TEST INJECTORS WITH THE CLEANING SOLUTION MIXTURE. THIS WILL PRODUCE FALSE TEST RESULTS. ONLY USE CLEAN GASOLINE.

In cases where fouled injectors were the cause of the driveability concern, it should be recommended to the customer that a better quality gasoline be used. The Owner Guide, Maintenance Schedule and Operating Guide address the fuel quality issue.

NOTE: IT IS VERY IMPORTANT THAT THE CORRECT CLEANING SOLVENT IS USED WITH THE ROTUNDA TESTER/CLEANER. THE CORRECT CLEANING SOLVENTS ARE: Power Flush Injector Fluid E6AZ-19579-C & Carburetor and Combustion Chamber Cleaner D9AZ-19579-BA

DO NOT USE Injector and Fuel System Cleaner E6AZ-19579-A
