I have a late model 94 tahoe with the 95 engine in it. i bought it and drove about 30 miles and it locked up completely due to a faulty mechanic with the previous owner no oil was reaching the engine after they replaced the spider. my fiances step dad got an engine of the same year from a scrap yard and replaced it for me but the new engine has problems too. oil i appearing in the bottom of the engine after driving and the engine is smoking. the steering is also starting to go out and its not wanting to shift when going uphill. Its also not wanting to go forward when the wheels are turned too far. I really do like this truck and dont want to get rid of it but i dont know too much about engines.
First of all,the spider assembly,also known as injector nozzles are located on top of the physical intake manifold,normally there should not be any conflict whatsoever servicing the spider assembly to cause any oil starvation issues. As far as your plethora of other problems,maybe related to your issue,but doubtful,you may not want to hear this but you really need to take this vehicle to a reasonable,also very competent technician to diagnose the list of problems,i strongly suggest that you cease any more semi pro help or the hole will certainly get much deeper!!!!
i cant really afford to take it to a mechanic and the one who replaced the engine is really good he has build engines from scrap that run good but the engine was old that we got i dont know the old mechanic from the previous owner all i know is what ronnie told me and he said there was no oil in the engine but it had plenty showing with the dipstick.

A tune up will not cure the lean code, in fact an engine miss gives a rich code from the unburned fuel. I would suggest u verify u have no vacuum leaks, also clean the inside of the MAF sensor if so equipped and replaced the bank two O2 sensor, that is the passenger side sensor before the catalytic converter. If u have the money replace both right and left sensors, it is better to do them in pairs.

that fuse feeds power to fuel pump relay circuit that feeds pump could be defective pump,or damaged circuit wires that shorts out! and not a good idea to put higher fuse in circuit could cause more damage to circuit! but i know when your stuck, u do what it takes,so inspect circuit related to fuse,

Hello;
The white smoke is from coolant entering the combustion chamber(s). Coolant can enter through the water passages sealed bu the head gasket. You have probably blown a head gasket. You should check your coolant level. You may have acracked head if you continue to drive it and overheat. The temp gauge only reads when exposed to coolant, not air. Take out thhe spark plugs and look them over. A white glossy apperance will indicate water in the combustion chamber. You may need to surface the head once you have it removed so that it is flat. Hope this helps.
Thanks;

The carbon on the spark plugs and black smoke coming out the tailpipe means you are running rich. (Too much fuel) this can becaused by anything from a bad Mass Airflow Sensor to a stuck injector to a leaking Fuel Pressure Regulator to a bad Upstream Oxygen sensor.
First, you need to check fault codes to see what the computer says the problem is. I would not be pouring injector cleaner in your vehicle unless you are absolutely certain the the cleaner you are using is going to be compatible with your fuel system. I've seen a lot of fuel system damage as a result of that.
In 2005 Chevrolet Avalanch had two different 5.3L engines one was flex fuel and the other was not.
The 8th digit in your VIN will tell you which engine you have. if it is a "T" it is standard gasoline and if it is "Z" it is a flex fuel engine.
There are several Technical Service Bulletins (TSB's) issued by GM for the fuel systems on BOTH of these engines. Depending on your engine type and the codes retrieved from the Engine Control Module, these TSB's may or may not apply to your problem.
