93 KICK , 1.6L 16V 5speed Thorley header
Fuel pressure , timing cam timing sensors check ok per FSM plus new caps in ECU
Problem:
slight dead spot right off of idle , and missing when trying to "PUTT" at 1,500 to 2,000 RPM.
What I found:
I plugged the vacuum line BEFORE the EGR modulator ... runs perfect.
hook line back up , plug EGR vacuum line AFTER the EGR modulator ...
runs perfect.
Hook EGR back into system , flat spot and miss return.
Question:
Should the EGR have an effect on the engine at this low of rpm?
Is the modulator or the temp sensor allowing the EGR to open too soon?
If the EGR is not hook up , will the EGR temperature sensor "LIE" to the ECU because it is not getting hot enough.
Thanks ( I hope)
