my car surges everytime on start up,even after driving for a while and sometimes while im driving ill push the gas a little and it wants to cut out but not bad but if i push it a little more it clears up and when i want to pass someone and push the gas like half way it starts to pick up slowly and then it kicks in like it should.its the same way when i put it to the floor(wot)it starts picking up and and it kicks in.lol its like driving a v6 with nos,floor it and hit the button.i put a new timing chain,fuel filter,all new gaskets and a full tune up on it and it runs the same:icon_frow .what can make it run like that???map senser,egr,tps???
 
I told you what it was last week. I'll try and make it up to Woodys later on and take a look. If not i can swing by tonite sometime.
 
How is your fuel pressure?? Clogged exhaust. Timing will cause it also.
the fuel press is good.new timing chain but it ran the same way with the old one.i think i might have a bad fuel press reg but im not sure.at wot it feels like theres not enough fuel.
 
i got a new fuel press reg today and im going to put it on in the next 20-30 mins after the car cools off.ill see what happens.
 
if you checked fuel pressure, and it was good. Why did you buy a new regulator and install it? A good diagnosis will save you money, so ur not throwing parts at it you dont need.
 
Do you have many mods done to the car? It may be running too rich. For shits and giggles remove one of the small vacuum caps from the vacuum log on the firewall and take it for a spin. That was an old E-cam trick back in the day.

i thought it could be sticking
 
Your MAP sensor could be fucked. I think Autozone can test most MAP sensors. That is if you can handle going into an god damn Autozone and waiting for 40 minutes while you stand at the counter and they answer phones.


I hate Autozone. :)
