98 Accord- Cutting out at low end between 1500 - 2500 RPM. Intermittent problem when car is at normal operating temp. No Engine codes. New Main Relay switch, EGR Valve replaced and ports in Air manifold cleared. Runs great and plenty of power at higher RPM's but when throttle is held around these lower RPM's it will cut out and them return immediately. Does always do this but now is happening over 50% of the time when car is warmed up. Haven't check fuel pressure regulator but it would seem that this would be a more consistent problem is it was fuel pressure related. No dash lights flickering and giggling key in switch has no effect. Thoughts anyone


3.0 V6 V-TECH Automatic. Doesn't matter if I'm on the road or sitting park the cutting out happens in the same RPM or throttle range. Intermittently of course but never goes below idle range.

 

Update: check vacuum lines with Carb cleaner and didn't notice any idling changes or flooding so if there is a vacuum issue it isn’t near the air intake manifold.

Still would appreciate any information if you have suggestions or have seen this issue.

 

I was going to say an EGR issue but you changed that,did you clean the connector?

 

I replaced the TPS and have verified voltage ranges are good so it seems to be fuctioning as designed. New plugs, Distributor cap, and rotor button. Engine sounds great except when warmed up it still cut outs sporadically in the low ranges whether dr4iving or sitting still. I can unplug the TPS when it is doing this and it will stop cutting out. Plug it back in and a few minutes later it will begin cutting out again. Still would appreciate any good advice.
