engine rpm surge. help needed.
#1
1995 sidekick 16v 4x4 auto 135k

Hi all. first post here. from USA.

not sure where to start here... only had the kick for a month.
ran like crap when i got it.. i just did the following...pcv valve ngk spark plugs gapped at .28. ngk wireset. Sandard brand cap and rotor. at this time i adjusted valve lash per fsm. (exhausts tight.. intakes loose) after everything was done after close examination i discovered two things.. 1. the accelerator pedal cable was adjusted too tight causing the plate to not snap shut...2. the kickdown cable was adjusted to tight causing the throttle plate to only open to 60%.... so after readjusting both cables (over and over because they slightly effect each other) i now have a throttle blade that snaps shut... with no negitive pedal play. and a kickdown that engages at 76% throttle and is maxed out when throttle blade is ~96% open. i did a compression test (cold/dry) and got 184-186 across the board with minimal cranking. (aka could have kept cranking to get higher results)

ok my issue... i now have an idle hunt/surge that was not there before (throttle cable out of whack hide this?) i can duplicate the issue eaisly. it does not surge at idle.. only under very very light throttle at 1900rpm. hold it at 1900 and it will dip to 1500 then back to 1900 untill you either go higher than 1900.. or let off to base idle speed (i have it set to 800) it will do this while driving too.. but only going down hill at 30ish mph and very very light throttle. this results in a pulsation while crusing. luckly i have 31" mud tires so the engine is always under load... with stock tires... i feel this would be annoying as it would be happening more offen (less load)

kick runs very very well now! minus this new probem no hesitations even when flogged from a stop with 31 boggers.. no problems doing 85mph on the highway.


things ive checked.. vacuume hoses all good.. pressed egr bladder while running and engine tries to stall. engine lamp is off but comes on with key/off when run.. engine gets up to temp. holds coolant pressure.

things im courious about but have not looked into. my new pcv valve i could blow and suck through. the one i replaced would blow through fine but not suck at all. made me question the quality of the new pcv valve. also. i did not adjust cam timing or ign timing as i have good compression. runs great. this is a new problem.... TPS... have not played with it.. but its a suspect due to the throttle cables being so so out of adjustment. (cables now ok)... i dont think im missing anything.. il attach a few pics of our patient. clamp on pcv valve was fixed prior to starting (its off in pic)... cant add pics.. too big
