There is an Idle control sensor that has likely gone bad, take it to a trusted mechanic or dealer and have them replace it to solve the problem--roughly $300 repair at a Toyota dealer

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?

I've got a 1996 jeep grand Cherokee with the 5.2 v8 fuel injected Holley throttle body. My problem is while driving at soft or low acceleration it accelerates fine, but if you hit the throttle hard it


I would check the voltage on the throttle portion sensor with the engine off from idle to wide open throttle.If there are any dead spots, replace the sensor. If the tps checks out, you should check fuel pressure. If you have good fuel pressure, you may want to make sure there isn't a lot of slack in your timing chain. I don't believe you mentioned the mileage of your vehicle. Best of luck.

Idles irratic and runs rough down road after warmed up


Rough on idle when the engine is warm means there are many areas to be checked and it can start with the ECM , the fuel pump and more likely the sensors, check the throttle valve, the camsensor which can be set off which might need a correction. Also the vacuum feed for auto advance needs to checked.

Rough idle and stumble through acceleration. The fuel filter, Pressure regulator, Throttle body and tps have all been replaced as well as a full tune up. The fuel pump runs 90% of the time and other times...


You need to check the fuel pressure to the throttle body. If the fuel pump is nearly worn out, it will display similar symptoms. Did you read out any codes on the computer before starting this repair? Good luck!

93 grand cherokee has a very rough idle what could be the problem


Also check the vaccum hose from the fuel pressure regulator to the intake manifold, it is right on top, to the front right of the valve cover where the fuel lines attach to the fuel rail, there is a small vaccum hose that runs from the regulator to the intake manifold, I have a 93 grand cherokee limited w/ 4.0L 6cyl, it was hard to start at times, wouldnt start at times without starting fluid spray and had your symptoms at idle, running rough like it wanted to stall like it was out of gas, I had various opinions ranging from fuel pump was bad to the fuel filter to the fuel presure regulator, the fuel pump relay ,etc....after replacing the relay and having the same symptoms, some digging brought me to this vaccum hose, wich had a break in it, when it was replaced it allowed the regulator to have the correct fuel pressure output and solved all the afforementioned problems way cheaper than the suggested alternitives. good luck.
