I'm hoping you all can help point me in the proper direction to assist my problem. I've searched and search to find the different scenarios I am experiencing but cannot find a solution yet.
Car starts up with little struggle from sitting for a day or two- once fuel is pumped in after a few seconds and a couple turns at the ignition, the car cranks and idles just fine. It runs from then on just great, great power when stabbing the accelerator and throttle is very responsive on blips.
My problem arises around 15-20 mins later almost like once the car is warmed. At a stand still the car will begin to sputter a bit and as time goes on, get progressively worse. It will then run OK with deep throttle but once you let off the sputtering returns and you have to feather in the throttle at a stand still to keep the idle going which will stabilize but is at a much slower rate now. A minute after that, the car will act like there's not lot of power and a rapid sputter will occur in the higher gears on throttle and run only slightly better in 1st-2nd gear. Then maybe 30 secs later the car acts like there's not enough power to propel it forward in any gear on throttle and sputters heavily almost til it dies ....you can recover it with throttle feathering and it will have a slow sickly sounding idle. The red light on the dash will faintly come on at this time.
My question is, where should I attack here?
I've replaced the cold start valve, voltage regulator (yellow tape), thermo time switch
I've checked the intake runners, one was poorly seated with a slight vac sound- I fixed it but the problem persists
My thoughts- something to do with once car is warmed up?
Zeitschalter- thermo time relay?
Bad fuel pump?
Bad Alternator?
(Stock engine with K-fish)
Any thoughts are appreciated- I'm a pretty big '02 newb and not very smart on car electrical/fuel systems
