FUEL MILEAGE NOT INCREASING!!!!

[razorback]

QUESTION!!! i have plate-cell generators on both my 95 chevy and 93 toyota pickups.my power has increased and the motor on both pickups runs quiter and smoother but may gas mileage hasnt came up like all the websites say it will.is the problem the e.f.i.e. i dont have them installed on either vehicle.neither is fuel injected but the toyota came out of california and has e.f.i stamped on the intake.the 95 chevy is port injected.i teed into the pcv vacume line goes into the port.CAN ANYONE HELP!!!!!

Hi there, hope I can help. First need to know the engine sizes and what type ( you mentioned plate, but what is the config?) and or how many cells you are using per vehicle? Well to start with both vehicles are (pre 1995.5?) OBD1 computer controlled. The Toy with E.F.I. stamped on the Intake usually means Electronic Fuel Injection, the G.M. with port injection mean just that, Injected (fuel). Yes the EFIE will have to be used to get max mileage and balanced operation. As for going to the PVC valve ( and what port? ) you will have high vacume ( you most likely read about this condition) at idle and steady cruise ( and really high off throttle gear down/ engine brake) and low vacume on acceleration. That is why some systems use two HHo feed lines to try to get around this vacume issue. Try installing the feed line before the air control unit ( not the air filter box ((you may have a air mass sensor that uses a heated element which could cause a backfire to the generator and if you do not have a "bubbler" or some type of aresstor there may be a issue. Have a good end of the year (have to be PC) E-H

sounds like both are fuel injected, so O2 sensors need to be compensated for.

definitely need a line going in before the throtle body, no vacuum at take off means teeing into PCV line means you will not be getting any HHO. Vacuum is moderate at cruise so you will only get moderate amount of HHO.
