finally got around to adjusting my valves friday. double check triple checked all my clearances. all are good. car idles fine unless i turn on the headlights. starts to surge for 10-15 senconds then smooths out. im thinking its electrical due to the fact it only acts up w/ the lights on. probally a ground? engine rpm would always drop then pick up when i turned on lights but never surged like this. any help will be rep'd thanks
car is a 95 dx w/ d16y8

well today my car was having irratic idle problems and not wanting to accelerate when i drive, ran a test on my ecu and it showed my fourth cylinder wasnt working right ad was firing off ? or something like that so i bought all new spark plugs and its back to normal dont know if it will help

yea im steering to the alt. maybe the voltage regulator inside is going out? the foglights in my car where wired to the parking lights i unplug them and the idle dips but pulls back up. maybe the alt isnt compensating enough for the load that the lights put out when turned on? ive got no lose in power. put brand new plugs in last week which were gapped to specs.

test the voltage coming out of the Alternator, my bet is on the regulator.

could also be fuel pump tps(throttle position sensor) and check your ecu codes

mine does that every day (not all day just when it wants to) im no tech but i heard mine could be the idle control sencer

just take your car to advanced auto parts or w/e and have them scan your electrical stuff. it will tell you whats wrong with it if it is the tps
