The car starts fine in the morning[7 am], fires right up and goes to a nice idle. I then to drive to school and the car sits till noon. When I try to start the car at noon, it will either not start[and flood the engine], or it will start up and then idle really low, and then slowly die. usually after it dies once or twice, i keep on the gas when i'm waiting at a stop light, and the car probably gets warm enough, and it idles fine. What would be causing my idle problem? I just had my lower intake manifold gasket replaced, which was causing me a huge idle problem before[wouldn't even idle unless i kept my foot on the gas]. I now have a switch wired to my fuel pump, so i don't really have to worry about it flooding, but it never flooded before i got my manifold replaced. I had a rotary shop do the work for me, and i'm gonna take the car back and ask them why it's flooding and having problems idling still. Any suggestions or thoughts?

I am premixing 1 oz of MMO per 2 gallons right now, and just replaced my spark plugs, and actually found out my L2 wire was going to the T2...but fixed that up. the car has 143k miles, could this be leaky injectors?

 

hmm, no one thinks they know whats up? I had my tps adjusted today, and the car has a rock solid idle now, but it still takes time for me to get it to idle on its own when i start the car up at noon. I usually start the car with the pump off everytime now, and then when it begins to turn over a little i hit the switch and activate it to get the car started. My mechanic is telling me low compression is the culprit when it has trouble starting warm, time for the atf trick i guess... hopefully my engine can last a bit longer, i don't have the money or time for a rebuild, and anyone know how much an engine swap might cost, i might start looking for a used engine with lower miles, but i dunno if i could swap the engine out myself.

 

oh btw, i'm still getting a reading of 12-16 psi on the vacuum side, usually sits at 14 when warmed up..

 

/\ /\ /\ Anyone? have any ideas? insights?

 

Try using some MMO and do the ATF trick. Do a search on it.

 

i'm doing the atf trick right now, before that did the water treatment...car seems a little smoother but i can tell injectors are bad b/c 1. it floods everytime i try to get it started 2. i get some hesitation once in a while when accelerating or getting on the gas hard when cruising. I have some techron fuel system cleaner i will use next time i fill up, i'm letting the car sit for 2 1/2 days with atf, and then i'll run more water thru it to get all the atf burned out and change me oil as well as plugs...this car has 143k miles, so i'm gonna be doing whatever it takes to keep the compression up, and yes i've been adding mmo to my gas. I'll let everyone know how the car runs once i burn all the atf out
