Car will crank and idle low but as soon as i push the gas it cuts off. What could be the cause of this? There are no vacuum leaks, the car has an auto ecu virgin p28, the timing is perfect (done three times) has a walbro 255. There its getting fuel becuase when i take off the fuel line it squirts. Ran the celcodes and its 22(vtec pressure switch, not hooked up), 14, and 41. One of those is iacv. That is all i know. If i need to i will post pics of the motor.

 

Bump

 

so your saying u have a stock p28 running a ls/v?? yeah i think that could be a problem.. fix the cels if its looking for stuff thats not hooked up dont you think thatd be bad?? is this on an autotrans??

 

You need to get the correct basemap for the motor. Your IACV is also your problem. Get it fixed.

 

I will try both of them....thankz guys

 

Yes its a stock p28 the car use to be auto...so it is a auto stock p28....the car was Uto but was conveeted before i bought it..

 

You also need to convert the ecu to a manual. Search for my DIY

 

ive put 2 blocks in my car because i thought it was the block and when i pull the spark plugs there is oil seating on my pistons i hope someone can help

 

Leaky Headgasket or Rings.
What is your setup?
You running headstuds?

 

tube seals leaking would cause oil on pistons. As for you idle problem. First fix the cels. Check for voltage and ground at iacv. When I say that I dont mean look at it and shake it. Get out a freaking dmm. if you dont know how take the car somewhere cause you wont get know where trying to shotgun it with parts.

 

Tube seals leaking would cause oil to be in the tube, not ontop of the piston.... Assuming your plugs are that it.

 

First, You need a chipped P28, for manual and a basemap for an LS/V. A stock P28 is made to run a SOHC not DOHC.

I also do believe you need to do the IACV 2wire-3 wire conversion?

 

its a stock b1 block with a b16 head arp head bolts

 

new turbo hew headgasket new intake gasket on a base tune on a chipped p28 and im running a ls headgasket. and there is oil on the exhaust side in the ports

 

your running an LS headgasket on an LS/v? there's your issue.

 

thats what everyone told me to run

 

the bottom of my head is welded shout because a ls dont have the oiler like the vtec block does

 

You ALWAT run the headgasket that matches the head. You need to read up on Ls/v conversions.

 

thats what i that but a shop told me to run a ls headgasket because me head is welded
