For some reason my car will idle normally till i get on it for the first time once its warmed up. From then on the idle will stay above 2 grand. I can turn the car off and back on and the idle will still be at 2 grand. I've found several problems and have corrected them... no change...
Set the base idle and timing
Regrounded maf and tightened the connectors (ecu was throwing a code)
Checked tps voltage (normal)
bought and installed an entire new idle assembly (130 from vogel at quality... great deal on that part)
found that the hose on the top of the activated carbon canister which purges the fumes into the intake manifold was disconnected on top of the canister (reconnected it)
Found that one of the plastic nipples from the egr and canister control silenoid (the one under the tb) had broken off. JB welded it into place... silinoid still working and reconnected hoses.
check the tb for something holding it open (nope closes all the way)
here's a question. the hose that attaches to the large nipple on the intake tube closest to the throttle body (the one that sends air to the air regulator) has a vacuum even when the car is warmed up. I believe that the air regulator is the only thing connected to that hose and therefore this would mean that the air regulator is not fully closed when the car is warmed up right? i tried capping off the hose and the nipple to the air regulator since the car was already warmed up and i can't tell if this made a difference. So one more question are the jdm and usdm air regulators the same part??? i know that the idle assembly is not neither is the tps or the temp sensor... but what about the air regulator???
thanks.... and i will tell the entire forum how to download nissan FAST
