Question about 1990 Chevrolet K1500

2 Answers

My 1990 k1500 4x4 350 Throttle body. shut off the other day when i was driving it without my foot on the gas. i figured it was out of gas so filled it up. It starts right up fine then dies. i can start it and press the gas barely to keep it going but it's loping bad and wanting to die and if i give it more than just a little bit of throttle it dies. i replaced the fuel filter, new plugs, wires, distributor cap and rotor. what might it be?

Your throttle body and components in it probably need cleaned or your egr valve is sticking.

SOURCE: 1990 CHEVROLET K1500 350 MISSES AFTER WARM

My first thought for a solution of your problem is plug wires. You have replaced some common problem areas for this situation but the plug wires are the most susceptible for causing a miss after engine is warmed up. Try replacing the spark plug wires and let me know what happens.

The crank angle sensor maybe bad. It sends a signal to the computer so the spark plugs fire up.

What causes engine to accelerate without gas?


Possibilities:
  1. Leak in intake manifold or deteriorated throttle body gasket;
  2. Loose or missing throttle body spring;
  3. Defective idle air bypass valve;
  4. Bad throttle position sensor;
  5. Bad EGR valve or EGR position sensor;
  6. Evil aliens.
If there is, or has recently been, a CHECK ENGINE light showing, have the stored codes read out. They may reveal the culprit or, at least, indicate where to begin looking.

replace the throttle positioning sensor on the throttle body. It will need to be reset upon replacing it so have a qualified mechcanic do it for you

1999 Dodge drangeo trucks been making a loud nocking sound only when it's on drive and holding down on braek and feels like it wants to shut off


its hard to diagnose a sound with out hearing it.but on the idle i would clean the throttle body. remove the hose or air cleanser from the throttle body. buy some throttle cleaner spray from the parts store. .open the throttle full then spray the cleaner on the black gunk. then with a soft tooth brush scrub the blade and barrel. then sprat clean. after reassembly start and let idle for three minuets in park the with your foot on the brake let idle for three more minuets in drive .do not touch the gas peddle.

Sounds like you have to much gas going thru the throttle body. When you put your foot on the gas it opens the airway and lets air and no gas. The black smoke is unburned gas. Replace the throttle body and you should be good to go. It could be the fuel sensor also, telling the pump the wrong info.

Car won't run without foot on accelerator.


its very important that the throttle body especially around the throttle blade be spotless clean or they will stall every now and then. then progress to refuse to idle at all. take off the rubber air intake pipe from the top of throttle body [has 3 torqes screws] open throtle by hand and look for carbon/grease/soot etc were the throttle sits when closed. clean with toothbrush and some caeb cleaner get all black off and dont forget the blade, both sides and the edges. scrub then rinse with carb cleaner untill shiny.spray some cleaner in the hole that is on top off the body to. that is your idle air controll motor port.put back together.it will be hard to start at first so hold gas pedal half way down untill it starts then slowly [real slow] let foot off untill you are no longer pressing it. put in reverse and let it idle there a few seconds then do the same in drive. that should do it. sometimes it may stall a couple of times when driving dont hold foot on gas just let it die then restart this allows the computer to readjust its idle stratagee

1990 ford probe-Changed air filter now it won't idle at all!


Check the connections to your IAC (idle air control) valve and or remove it and clean it - do the same to your MAF sensor located just behind the air filter box, you will need CRC mass airflow sensor cleaner and a T20 torx bit, look for vaccuum leaks as well
