(Accidentally Closed This Question) - Car Shakes When Start Up - Check Engine Light On?

blinking light means misfire, there's something going wrong with your car random misfire... hmm... did your mechanic do a full tuneup? plugs cap and wires? it may be a worn distributor cap, could be your spark plug wires are crossed or grouped up together that would cause a random miss... EGR valve stuck open could also cause this, Air filter extremely clogged again could cause this it is happening at start up and first startup so we can rule out carbon buildup in your cylinders... could be compression issue but again that would be just one cylinder... my honest opinion would be Check your wires, make sure they are not touching electricity can jump between them on rare occasions Check and clean your EGR valve, it may be stuck open Check and replace your air filter Check with your mechanic see if he did a distributor cap, if not get it done from there its really anyones guess, but there is a massive misfire going on and its random which points me to those three points right there.

1. My 2000 ford escort zx2 isnt starting?

the emblem of plug is an argument of selection. There are also a number of sorts. All that are indexed on your motorcar will meet OEM specs. i do no longer, as some different person printed, like champion. I run Bosh platinum because i think i am getting more beneficial gas economic device and bigger performance. A parts homestead is a sturdy position to purchase plugs because the fee is close and also you will have had a human being that would have helped you. you likely would have the remarkable plugs by utilising now. maximum folk do no longer do not ignore that a motorcar does no longer ought to truthfully omit to run poorly. A motorcar is timed, partly, by utilising the era of time it takes for the spark to get from the source to the very tip of the spark plug and ignite. that's termed the firing time and measured in milliseconds. As spark plugs placed on the gap between the probe and the electrode widens causing the spark to take longer to ignite the gas. This, in outcome, retards the timing. On more moderen automobiles the computing device will attempt to make amends for this causing, at ideal, a drop in gas economic device. yet an additional reason behind poor gas economic device and performance issues is even as the plugs misfire. there's a production unit suggested upkeep agenda for plugs, air filter out, gas filter out, and different issues which could be observed. in case you personal and rigidity a motorcar and do not have a human being that keeps up with this then you actually could. this can help preclude you from sitting someplace broke down and extra prices. examine the owner's guide to understand upkeep schedules. this could also include the variety of plugs suggested. also be careful in case you intend to modify the plugs. that's a basic interest yet care could be used. If a plug is extremely tricky to eliminate provide up. you may want to strip the plug threads. also use care no longer to bump the ends of the plugs and modify the hollow. even although new plugs are pregapped I continually verify them. a sturdy pregapped plug would have a tricky cardboard type sleeve round it to guard it from harm

2. Dirtbike won't start--sat for over a year.?

Spray WD40 in the carb (remove air filter) while you start it. If it stalls down, just repeat. Let run for a while till it clears the varnish from carb and tune up when warm

3. O2 sensor for 1999 Olds Intrigue 3.5 motor ?

O2 Sensor? Probably NOT the problem. People like to blame the O2 sensor for the problem because that's where the computer fault appears. However, nine times out of ten, it's not faulty. It is simply reading a condition in the engine that is causing it to send a signal to the computer that there is a fault in the exhaust emissions mixture. A fouled spark plug, loose spark plug wire, a vacuum leak, dirty injectors, EGR valve, weak fuel pump, dirty fuel filter, weak ignition coil, plugged air filter, on and on, can all cause the O2 sensor to register a fault code. Before you yank the O2 sensor and replace it, check the basics first. Otherwise, you could have wasted time and money on the result, not the cause. (Check Engine Light) There are many components that work together in the engine to maintain optimal engine performance and economy. A "check engine" light indicates that there is a sensor that is reading a condition that is "out of range". Simply resetting the light does not solve the initial cause of the problem. Replacing a number of parts trying to troubleshoot the problem in the hopes of getting the light to stay off is a tremendous waste of time and money. The simplest, and most economical way to alleviate your issue, is to have an engine diagnostic done by a reputable shop to determine what caused the computer to signal you to begin with. Just reading the computer codes may not find the "cause".
