Help me solve my Hesitation

[Bluestreak]

OK I talked a bit to some other people on this and I was told to clean the MAF so I did and no difference.

Its most noticable in 1st but it does it whenever I'm getting on the interstate but not as bad or as noticable with the other gears.



SO Any help would be great !

Thanks in advance!

Have you check for codes?

Possibly Spark Plugs? wires? just check some igniton parts

 

[Bluestreak]

no codes.


I have everythign for a tune up, but the intake gasket so I haven't done that yet.

The ones between the heads and the manifolds? Pm me for a set with 50 miles on them.

wierd! i just posed on a slight hesitation too, its most noticable in first gear, espicially when its first being driven in the day, like for the gas its getting its just not picking up the RPMS as it should, but even in second it improves alot. Changed my wires, plugs were fine still to no avail, i get no codes, and i have a feeling cleaning the MAF isnt gonna do it. Let me know if you solve this problem as i'd be interested in knowing how!

what do you mean by hesitation..?

..well it might not be a bad idea to check fuel pressure?

 

[Bluestreak]

Fuel pressure was checked and it is right on speck.

 

[Mrhappytuzi]

wait.. explain what this hesitation is exactly.... cuz my car will like hesitate around 3900 - 4200 rppms.. well its not like a hesitation but its like the car wants to go.. but it just... doesnt want to go. but i beleive that to be because my secondaries will not open for some reason..

Plug wires

 

[Mrhappytuzi]

Meh, for some reason i thought it said that the plug wires were changed... bah i know my cars needs plugwell seals bad.. and also wires n' plugs

 

[phreaksho]

i to also have this hesitation but it is only when i first start the car for the day and only in the first right when it is started up

 

[Bluestreak]

MIne is when you shift into first, you give it some gas, and it doesn't want to really go, then it catches, but you can still feel the hesitation when you are going throught the gears, getting on the interstate. I replaced the fuel filter and i have the stuff for the tune up but I need the plenum gasket so I haven't done the tune up yet.

My SHO does the same thing. After the car has warmed up for awhile it doesnt do anymore.. yeah ive been trying to figure that problem out for awhile too.

Wires for these motors are very picky. They could be new and as soon as there is condesation "if they dont seal good enough" in the wells they will be shot. You should be about to see a carbon arc on them if they shorted out

again, another reason why you shouldnt pressure wash your motor... i think i argued with luke on that one, matter of fact im sure i did


it sure does clean nicely though...

 

[Bluestreak]

You never pressure wash a motor, and if you hose off a motor, you still have to be really careful.

 

[phreaksho]

not PRESSURE... lol use a pressure washer but not on the pressure settings... to get a good degreaser/water mix.... we did this at the dealership all the time to get the engines ready for the shoroom... and also when i wash myne i wrap up alot of things but at ewalds we just sprayed em down and wiped them off

 

[phreaksho]

also my hesitation only started about 1 week ago and only when cold... i havent washed my engine in a year or so only. i think it might be battery related cuz im having lots of idle problems and my batterly light is on everytime i start the car... now i just gotta come up with the money for a optima
