Non start at times?! HELP!!

[jonosranger]

Ok guys i need some help with this. My car has been getting worse. Some times you can go outside and go to start it and it starts within a half a rotation of the engine. And other times it acts like it is flooded and you have to mash the gas pedal to the floor to get it to start. And it kinda stumbles for a second and runs fine afterword. And when its cold it will idle fine. But when its hot it will idle roll really bad untill it dies. check engine is not on and yes it works lol any help would be great

[EHardy1971]

Sounds like either the coil breaking down,or the TFI module.

Just because the check engine light isn't on doesn't mean that no codes are stored. I would pull the codes and diagnose from there.

Is this the '90 model from your sig? Or the '88? If it's a MASS AIR car, I would start by cleaning the element in the meter with some carb-spray. Then do the basics first, like plugs, wires, cap, rotor...and look at the TPS voltage. These simple things might fix it.

There is also something called a "Thermactor Air Bypass" solenoid which is picky about cold-starts. It's a little solenoid with a grey cap on it, located on the back side of the passenger-side shock-tower (see pic below). The little cap can be popped off and there is a foam-filter inside... it's glued down lightly, but you can easily take it off... blow the dust out of it with an air-blower and re-install with the cap back on. For some reason, if those things are dirty, they can cause havoc.

Yes it is the 90. Its not stock so that dont help maters any. All of the plugs,cap, rotor and tune up stuff is fairly new. I have cleaned the maf a few times. And i dont the have "Thermactor Air Bypass" solenoid or any of the smog stuff.

[TheJeanyus]

Have you cleaned the IAC valve? Checked for vaccum leaks?

[jonosranger]

yes i have done those two things

[jonosranger]

anybody have anything? I cant even drive my car. Because it dies so much

[SlowJoe]

I have been sprayin it pretty hard lately like through the half mile or better :jester: and im serious. And there are cars 3 times faster down here than urs :jester: Jk Im kinda pissed off at the moment:bs::bs::bs::banghead::banghead::banghead: and yea ima gonna do that maybe in a lil while

[SlowJoe]

maybe a intake gasket

[jonosranger]

it shouldnt be cause i glued them last time cause it was suckin oil really bad

[SlowJoe]

i know i know its the fuel rail hold down tabs:jester:

[jonosranger]

LMAO!!!!!!! And Yea its still like that LMAO!!! :jester::jester::jester::jester::jester::jester: i had to replace the zip ties the other day

[EHardy1971]

Did you try disconnecting the battery and letting the computer reset?

[jonosranger]

which time lol :jester:

[EHardy1971]

which time lol :jester:
Ok,what about the 10 pin connectors behind the intake? Sometimes they'll get shitty connections,and/or crud in them that will give you fits.

I know you have changed it already but it sounds like a intake gasket to me. If you can get it to start up try to spay some carb cleaner around the intake to see if it will rev up any.

[jonosranger]

ok i have an update. I changed injectors and it fixed all of the starting problems. No more having to mash the gas to the floor. On another note. I am guessing i am having mass air or ecm problems. I have found 1 maf that will run my car. I have tryed about 6 different sensors all which make my car idle roll and die. the one that will run it is off a friends car and i cant get it.

[jonosranger]

o And i pulled codes and have fixed all the problems with that.
