Usualy when car is bac fireing its the leads or spark plugs, if u hav changed them, itl be a fuel problem i.e fuel pump fuel filter even injectors if there stock and you are runing over 20psi they will be peaking out. if not then the only thing left would be your boost solinoid. earlier models have a boost cut at 14.7psi if running stock ecu hope this helps.

Camshaft sensor very likely. Heat is causing it to fail. Could also be crank sensor. Cheap part to replace, very easy if camshaft (top of engine) check that first.

I changed my front 3 spark plugs and a broken wire now and i have very bad rough idle and i could hear clicks? whats going on? should I put the old ones back on? the new ones were bought from...


The spark plugs should be matched up with the old ones to be sure that are the same as the new spark plugs and that the threads are not too long or too short and if the spark plugs were pre-gapped or if they need to be gapped, and the auto part store should have given you that information along with any spark plug gap because some spark plugs you can not set the gap on or they will be damaged. The spark plug gap should also be printed on the emission label out under the hood. Also, the other three spark plugs and wires should be changed to complete the ignition tune-up.

The spark plug gap should be the same amount between all of the spark plugs, and the farther apart that the gap is between the spark plugs the rougher the engine will run and idle, and the closer that you get to the same spark plug gap between the spark plugs the smoother the engine will run and idle.

It is also very important that the spark plugs be connected to the correct terminals on the coil pack or the engine will have a severe mis-fire and it will set a mis-fire DTC (Data Trouble Code) and cause the check engine light to come on.

Here is a firing order diagram to help assist you and let me know if need help with this diagram or if you require any further assistance.

I have a '94 vette and my issue is that I try to start the vehicle and it just turns over, wont hit and run, i know its gettin fuel but im wondering if the problem could be the diaphram that is under the...


its either the battery , worn plugs, or a fuel delivery problem...purchase some starter fluid, take off intake cover have someone try to start the engine...dont over do it, if it does start it could be the injectors not firing, or fuel pump not supplying proper pressure. Check battery voltage, it MUST be 12.5v minimum..have someone or AAA give you a jump, if it starts then its your battery. If your battery is good 12.6> and the starter fluid didn't fix it, then it has to be a spark issue!!..take one spark plug out and inspect your gap, is it extremely wide?...because if it is, it"ll have trouble starting..re-gap or better yet, just replace the plugs.Check your spark plug wires at the coil packs take off wires and look for carbon tracking deposits clean it up with some carb spray, and wipe down and look inside the boots and terminal post for corrosion.

'95 cutlass ciera, Mating the trans and engine?


Hi
Fit the torque convertor to the gearbox first, make sure it locates fully with the pump drive on the g/box(the round section that's got two flat sections) in the centre of the bellhousing. Make sure the convertor does not slip out when mating engine and g/box, when mated there should not be any gap between engine and g/box(transmision) without any bolts tightened, secure transmision to engine then only replace the bolts that holds the torque convertor to the flexplate.

Regards
Phillip

I bought a Subaru Impreza STI 2009 model .. What kind of the oil used in this car and is it Syntihtic oil?


i have an 05 sti. its the same motor as the 09. you definitley want to use a high quality full synthetic oil 5w-30. check the level often because it is normal for this car to burn a little oil do to the turbo. especially if you start making performance mods.
