Question about 1995-1997 Chevy 1500 Truck Ignition Starter Alarm Switch
1995 chevy 350 5.7 ltr egr problem solved I have had this frustration with my 1995 chevy c1500 350 5.7 ltr , no codes show up, but it stumbles around 1500 rpm. I checked sensor after sensor and even changed a few. I had replaced the motor with a crate motor and at that time I put a new EGR valve on. It runs fine when the egr valve solenoid is unplugged. Well it turns out that the auto parts store gave me the wrong egr valve, Thanks Advance.. The correct one is the BWD EGR 101D which is a referenced to the OE number 17113371. I changed it and it runs fine.
Take off your EGR valve and clean it out with carb cleaner also
grease tyhe little screw thing in it,,, u will c what i mean if u take it apart. carbon builds up in the chamber. it is located at the back left side of your engine and is a bit of a pain to take off. this should save u the cost except for the cleaner and labor. i had the same problem cheapest i found was 90$ on ebay.

It could be a knock sensor,crank sensor, or vacuum leak. Best information I can give you is www.alldata.com Costs about 25$ a year, however, it will tell you where every nut,bolt,wire,ground,power, and diagrams for every single part in your Truck based on your vehicle's VIN. I have used this service on my 01 Denali since the warr expired and it has saved me thousands of hours and lots of aggravation. It also lists any Technical Service Bulletins on your vehicle as well as "How To's" Hope this helps.

something is creating alot of air to pass over the 02 sensor.
Big vacuum leak.
IAC stuck a little open.
TPS that is saying your foot is on the gas when it is not.
EGR stuck open a little.
Too low an idle
Weak spark plugs
Bad fuel pressure regulator
No vacuum to the fuel pressure regulator.
Bad coolant temp sensor.
What are the readings. Need to know the co and the hc reading in order to know if you have a misfire or an over fueling issue. All 5 reading are really needed to diagnose fuel related issues sight unseen
