    take it to any autoparts store and they will check the code for free, it may have something to do with the fan or the injector seal was pinched and car is running lean could be lots of things, they will pull the code and give it to you for free then comment back on what it is.

I have a 95 camaro with a 3.8l. It had a #1 cylinder missfire code, I found out it had a bad fuel injuector so i replaced it. Now, it's showing a random misfire code. What could cause this change


An intake vacuum leak can cause this as well as other issues, read about it below.
Check Engine Light On, P0300 Random Misfire Code A random misfire means your engine is misfiring, but that the problem is not isolated to one or two cylinders. It is jumping around in a random way from one cylinder to another. A random misfire code usually means the air/fuel mixture is running lean. But the cause might be anything from a hard-to-find vacuum leak to dirty fuel injectors, low fuel pressure, a weak ignition coil, bad plug wires, or compression problems. Even a dirty MAF sensor can cause a lean code and/or misfire to occur. The engine may be stalling because it isn't getting enough throttle opening. The cause is often a problem in the idle air control system. The first thing to check is the intake vacuum with a vacuum gauge. On most vehicles a normal reading is 17 to 21 inches Hg. If the needle is lower, is jumping up and down or steadily dropping, you have a vacuum problem. Look for possible vacuum leaks by checking vacuum hose connections, the throttle body and manifold, and PVC valve and plumbing. An EGR valve that is leaking can also act like a vacuum leak and cause a random misfire. The next thing you should check is the fuel pressure with a gauge. If it is not within specifications (refer to a service manual for specifics because fuel pressure is critical for proper engine performance), the problem may be a weak fuel pump, low voltage to the pump (check the relay and wiring), or obstructions in the fuel line (like a plugged filter). A bad fuel pressure relay can also leak pressure and prevent an otherwise good fuel pump from delivering full pressure to the injectors. Dirty injectors can also restrict fuel delivery and cause a lean fuel condition. Many regular grades of gasoline do not contain adequate levels of detergent to keep the injectors clean. Frequent short trip driving accelerates the buildup of injector deposits. Cleaning the injectors with a good quality fuel tank additive (or having them professionally cleaned) can solve this problem. Look at short term fuel trim (STFT) and long term fuel trim (LTFT) with your AutoTap Express DIY. If the numbers are high, it tells you the engine is running lean

My 95 olds cutlass ciera will start up and run for about 5 minutes, then start sputtering like it aint getting no gas, slow down then die till it cools off then starts back up, putting again, losing speed...


Check spark at spark plug using a spark tester and fuel pressure at the rail when it acts up. If the pressure is ok at the rail, but the injectors aren't firing, that can point to a bad computer.If the fuel pressure is present but the spark is not being supplied to spark plug wires to spark plugs, then an ignition module might be in need of replacement (the metal plate the coil packs sit on). If the engine has a service engine soon light before it dies, maybe check the codes that should be stored in the computer using an OBD-I scanner.

check your wiring for dirty connections or broken wires, you may have wires that are rubbed through or connectors that are not making full contact. you will need an ohm meter and check wires for continuity. a wiring diagram will be needed.

1988 oldsmobile cutlass ciera check engine light on then stalled.


Wow! thats verry low miles for an 88. Check the fuel pressure at the injector. If the pressure is low the filter could be clogged or the pump is not putting out enough pressure. Replace both if the pressure is not up to par. also check the fuel relays.
