Why car idles out at high altitudes.


What do you mean by "idles out"? It dies? Perfectly normal, as at high altitudes air is thin and car runs too rich. One might think ECU would know this, but I think your car uses air mass flow to set fuel curve, rather than MAP.

Need an emissions schamatic for my 1984 K10 silverado 305 engine


Unfortunately, there are 13 variations for this engine and year. Was this truck sold or modified for high altitude? Was it sold in California or modified to meet the CA emission standards? Does it have a manual or auto transmission? After narrowing down based on answers to these questions, there are still alternative configurations depending on the particular equipment, so look carefully at the diagrams to see which components are used on your engine. Sometimes you can match the 3 letter code for the diagram to letters in the VIN or a sticker in the engine compartment. Please let me know if you have questions.

Rough idle low altitude smooth at high altitude


the carb is dirty, high allitude yields less air and more fuel, a richer mixture, overhaul the carb.

HP increase at elevation using a Dyno Jet Dyno?


same dyno? same operator? theres something wrong. the lower altitude the better, as far as I know. But someone thats smarter than me and has high altitude /dyno experience would be better to answer the question.

2001 Accent stick shift sputters in low gears and at high speed.


I suspect the timing is off since timing belt replacement was mentioned. The altitude would be read by the various sensors in the engine and computer and would be compensated accordingly.

Sir
when the fuel nozzles are partly blocked this type of defects are experienced. Try "wurth nozzle cleaner" and see.

My engine light came on. error codes show P2195 and P1166


The fuel pump is vapor locking, common problem in high temp/altitude states. Call the dealer and see if campaign t-13 applies to your car, if the car was originally sold in a low altitude state, it won't apply. I recommend the fuel pump be replaced with updated fuel pump sub assy.
