1986 Toyota 4Runner. Warning lights: Check engine light. Repairs for this problem: Just made sure the grounds were clean, and new injectors.
Question: in my Toyota 4-runner. When i turn the lights on the RPM's drop just a little , and if i hold the throttle at a steady spot it sputters a bit
, other than that it runs OK , just wanted to know where to start , to get her purring proper . thanks.
Answer: Any time the check engine light is on the first step to diagnose any problem is to scan the computer for any stored trouble codes in your Toyota. The codes would give some indication as to where the problem is. I would think idle air control. Turning the lights on does place a load on the motor and I would almost say the engine slowing down slightly would be normal. Holding the throttle at a steady engine speed and having it sputter, sounds like a possible EGR valve problem, or a spark plug wire is arcing causing a misfire. Again, the computer codes would help a lot in diagnosing the problem in your truck.

Toyota Engine Misfire
Question: new spark plugs fitted two months ago which proceeded to result in misfiring, took to another garage who discovered plastic lugs on all 4 plugs and leads, spark plug cap connector broken - wedged in plastic lug. The lugs have remove before use imprinted on them. Original garage response: spark plugs are all different sizes and some require that you leave these plastic lugs on to obtain a good fit. Is this correct? Since visiting garage no. 2 car does not misfire.
Answer: Well it would really help to know what the heck kind of car you are talking about. My guess is that it is some sort of foreign car, with a four cylinder engine. I guess a Toyota since it is that category.
With the words "remove before use" imprinted, this is from the factory and should be followed. Shop that says all plugs are different sizes does make any sense. An engine takes the same plug size on all cylinders. That goes for a Toyota or any other car.
My guess is that the cap problem and removing the plastic from the spark plugs fixed the engine misfire.
Comment: Whoever installed the spark plugs originally messed up. They did not remove the protective sleeve from the spark plugs. This caused there to be no physical connection of the spark plug wire to the spark plug. That will for sure cause a misfire and check engine light on your Toyota. A code p0300 is probably now stored in the car computer. The cylinders with the plastic still on them were not firing and causing the misfire.
It sounds like the first shop is just lying to you to cover that the mechanic messed up the repair. If they admit that, then you would want your money back and for the cost to repair it properly. They are just covering for a bad mechanic. There should never be anything on a spark plug between the plug wire. Not an on car, either it be a Toyota or any other car. These need to had a perfect connection for the proper voltage to flow to the plug so the cylinder can fire.
Toyota EVAP Codes Won't Start
2003 Toyota Corolla. Question: My check engine light went on. Took it for diagnostic which revealed an issue with EVAP system. When I brought it home I wasn't able to start my car ( I have a remote car starter- Audiovox Advent Pursuit PROOE4B Transmitter). The car won't start when I put the key in the ignition and I'm unable to turn off the alarm using the remote. I replaced the battery in the remote, but it still doesn't work.
Any suggestions on what is causing the problem?
Answer: The check engine light scan code for the evaporative emissions system would not cause your Toyota to not start. The after market alarm and remote start could be causing your problem. First be sure to check all fuses. If you cannot shut off the alarm with the remote, then I would say this is where your no start problem is. Either get it to the company that installed it or have the installer come out to you. These systems are usually lifetime warranty. If it is determined that the alarm is not the problem, then next you would need to find out if you have spark, fuel pressure, injector pulse etc.
