The entire exhaust system is cr p, so I'll have to save up for a nice catback exhaust with headers. Same thing happened to me back in January. Take the truck to Auto Zone and they will plug into the computer and read any codes for you. Dec 28, 2015 For this types of problem,there are few help inks to troubleshoot the problem. How is fuel filter and air filter? Interesting, not sure what the symptoms of a bad fuel pump would be. Hopefully not a poppet injector. The idle did sound pretty rough though when the problem began.
This part could be either battery or starter related. I would appreciate any help at all with this problem! Sorry O2 sensor was only the driver side, passenger side was not done yet. The next day I went out and the problem had returned, so it doesn't happen all the time, but it happens more than not. If it jumps around a lot, your chain has jumped. Also when testing fuel pump and pressure you need to tape a gauge to outside windshield or outside mirror and drive it on the road for 20 -30 minutes until the pump gets has run a while to check for a pump fading out after hot. Maybe a loose bolt - or something else? There is an 90% chance that Cap and Rotor will fix it. I am not new to internet forums, in fact I use to be a moderator on one until I got tired of being not much more than a babysitter at a daycare.
I have tried to put everything wrong and that I have done in this post that I can think of, if y'all have any more questions feel free to ask. I am hoping that this was indeed the problem. Hard to start cold and fuel pressure testing guide line. I finally took a chance and drilled a hole right above the passenger side cat. The Check Engine Light does not illuminate when I cycle the key or turn on the vehicle. Im not sure if your on a distributor or coil packs but one of my coils was starting to fail, not enough to throw a code at first but eventually it gave me a misfire code.
The only true way to clean fuel injectors is with the kit that you buy. I'm wondering if there's a problem somewhere like bad intake sensors or something. I have a 1988 Chevy K1500 5. Then shut it off and watch for fast leak down. The cats are about 2 or 3 years old. And someone will help get you started on some proper testing. My question is: It bogs out inbetween shifting, never stalls of idles rough just kinda boggy.
I had the same thing like a month ago. Oil pressure can drop once the oil warms up and becomes thinner. I have gotten to a point where I can't figure out what is wrong with out. Know of any good automotive forums where I could pose the question to get some more opinions? Vortecs are famous for injector problems of all kinds. I have a 1988 Chevy K1500 5.
Not sure if this is related to the rest of the problems but I think it's possible. I've read and heard elsewhere that it could be the Catalytic Converters? When I cranked the truck it sounded like a air compressor lol. The wire I saw the sparks coming from I inspected when I took it off, and it had two spots where the insulation on the wire had cracked and the wire in the middle was exposed. The best way I know to find an intake leak is to spray unlit propane around the intake with the engine idling. I changed it about 4 years ago. Could I have patched the problem temporarily, or did I fix it? A quick test is to block off the return line and see if fuel pressure comes up to 75-85 lbs. Another thing you can check is what amps the fuel pump draws, especially since you said it got worse after running for a while.
Those nozzles were famous for clogging. Even if it were a torque converter issue you would still get a P code indicating that there was a code stored in the trans controller. Thanks for the feedback My truck has felt wrong since i got it and gets worse mpg than my last truck, which had the same motor had to get a new pcm last week, now it's showing knock sensor codes, and throttle body codes. How many miles on tune up? Here is another thing I can turn the ignition off for 10 seconds or so and it does ok for a couple of miles before it starts again. Has a hard time accelerating from a stop, and sometimes will stall or bog really bad.
I will clean it tonight and see if that helps the cause. Replacing the fuel pressure regulator fixed it. Same thing with the upstream O2 sensors. My opinion based on your symptoms is a restricted cat conv. Airtex or el cheapo aftermarket fuel pump? It developed a fuel leak from the lines near the tank about 7-8 months ago and I didn't want to deal with it during the winter so I let the truck sit until the weather got nice and I was able to replace the whole fuel system from the tank to the motor not the injection system.
Hard to start cold and fuel pressure testing guide line. It will not start at all. Some simple things to check. I have also taken the air filter housing off and started the truck to see if the injectors are giving an equal amount of gas and they are. That's when you turn the key on all the lights on the instrument panel should come on for a few seconds. I would appreciate any help at all with this problem!
