1990 Chevy Scottsdale 1500 wont idle when first starting cold

After a few times starting it and reving it up, it will run fine no problems, and if I cut it off after warm it fires right up and idles. But when I first start it after sitting a while it fires up and bogs right back down.

Chevy Malibu Cold Idle Problem


Check the water coolant thermostat. If it is stuck in the "open" position you are heating up all the water in the coolant system and this will take time. The thermostat keeps the water in the engine until warmed up to almost normal running temperature, only then does it allow the coolant to enter the radiator.

My 2003 chevy tahoe won't start in the morning


Many possible causes....Too little info to make an intelligent suggestion. Try charging the problem vehicle's battery with jumper cables for 2 minutes with the supply vehicle running at fast idle (or about 1500-2000 RPM, if it is tachometer equipped) before you try to crank the problem vehicle on a cold morning. If it starts right up, you likely have a weak battery that needs replacing.

I have a 1990 Chevy 1500 SS truck with a 454ci. that has an idle


You don't have to try both, but...If you can get a scanner hooked up, you can see the TPS move as you depress the throttle, and verify if it is good or bad. The IAC can also be viewed with a scanner, and they get gummed up, and most can be cleaned.
Also, a bad temperature sensor can cause a high idle if it thinks it's real cold out.
Also, a bad power steering pressure switch can cause a high idle.
All of these can be looked at with a scanner!

Hesitation , skipping,engine cuts out when accelerating


Im having the same issue I believe. I have a 94\' Chevy 1500 and when i accelerate it will jerk like the gas has cut out but it wont stall. It just jerks and slows me down. It only seems to do it when going up a hill. I feel like it could be the fuel pump or possibly some intake gaskets?

1990 chevrolet 1500 pickup starts hard when cold


Most likely the coolant temperature sensor for the vehicle computer. Secondly, could be the tps sensor "throttle position sensor" not registering correctly or perhaps lots of other things but most likely the coolant temp sensor.
