Question about 1996 Oldsmobile Achieva

1 Answer

I took my car to have the codes ran. It comes up with a random misfire code. I have changed the MAP sensor, fuel pressure regulator, fuel filter, complete exhaust, spark plugs, boots, coils, and had the ICM checked by a couple different shops, car will run (roughly) and after 10 minutes the new catalytic converter will glow red..Any advice would be helpful. Thanks

Car running rough and misfire has various reasons, as you have tried most of them except the EGR valve , Check it out.

The symptoms show you have an faulty EGR valve . Replacing it will cost you around $50.

I have a 98 chevy lumina with 61k miles.what can I do about these codes, P0300. P1381


P0300 is a random or multiple cylinder misfire, and P1381 is a misfire EBCM (Electronic Brake Control Module) or PCM (Powertrain Control Module) Since you mentioned replacing fuel components, it could be as simple as a fuel injector being clogged up causing a cylinder misfire. Have you checked your fuel injectors?

No a knock sensor can not make a misfire. Check the coils, plugs and fuel pressure .The random misfires are cause the knock sensor to throw the code.

The plugs and crank sensor could have done it, but the TPS and idle air control would have nothing to do with a random miss.
A more likely cause is the ignition module or a fuel problem. You may have to wait until the problem is bad enough to kill the engine or you have more codes to check out.

I have a ford v6 3.0 dohc i changed plugs and wires fuel filter and fuel line pressure sensor had five codes come up the car starts properly took for a test drive and ran well but shut off when i stop


Code 191 is fuel pressure range-performance.
Code 172 and 175 are O2 sensors reading rich.
Codes 1132 and 1152 are O2 sensors not switching.
Under normal conditions, the fuel pressure should be around 40psi.
The pressure sensor is reading the pressure is too low or too high.
The O2 sensors should be switching back and forth between lean and rich. They are both staying rich.
Based on that info, I would reason the fuel pressure regulator has failed, or the return line to the tank is plugged.
The engine is getting too much fuel and the computer can't control it.

Rough idle random cylinder misfire


misfires are more from problem injectors, low fuel pressure or injector wiring than from plugs
have a fuel pressure test done to check for problem pressure regulator , problem fuel pump , blocked m/dirty filter
one other area of concern is the EVAP system where the purge valve doesn't vent the tank properly and causes low fuel flow rates

The only thing left would be fuel. Check fuel pressure , replace the fuel filter, and check the injectors(ohm's from 11 to 15) and the injector harness. Mostly on the harness make sure you didnt pinch a wire putting it back together, especially the map and coolant wires.

After going over 40mph the check engine light goes on n it gives the code 440


How did you read that code on your car? A 92 Accord is supposed to give you pre-OBD honda codes, which are all below 100. Please check the code again and re-post it.

This realy sounds like a fuel problem filter or the pump you are getting to many codes at once and all of these sensor can,t be going bad at the same time Looking at the random misfire and the fuel trim issues map and air charge all at the same time is unlikely The olny other thing you may wan,t to check is the crankshaft pisition sensor but aren,t getting that code so im thinking fuel delevery good luck

Your fuel pressure is low change fuel pressure regulator if pressure doesn't raise to 55-60psi your fuel pump is failing, change fuel filter also.

One thing to check is the fuel pressure regulator.
If the diaphram is leaking it will cause gas to be pulled into the vacuum system causing lots of white smoke and extreme rough running.
