Florida Drifters I need your help. My car turns on i can actually finally drive it.. but i cant boost. Driving the car is 1st gear and maybe giving it 3/4 throttle or mashing it the car sounds fine and the afrs look ok.. then i try in second gear and out of nowhere while climbing rpms my car stops increasing rpms and spits like crazy out the exhaust if i let go for a minute and drive the car like normal..it drives.. then on my way home while driving most of my afrs are super close to lean ---...in first gear everything seems fine in 2nd gear its 3 bar lean so bad i cant increase rpm much and its spitting like an rx7 at idle....i want to drift aftermath..anyone?

Can I get a little more background. Did this problem start after turboing it or just begin out of the blue?

For starters i would contact Enthalpy. They are always very helpful, you can even send in you're ecu to check for faults.

When the car starts spitting how are the AFR's? Whens the last time you timed the motor?

when its spitting the afrs are leaning out...it happened out of the blue..

Start by pulling codes if you haven't already.

I am guessing your fuel pressure gauge is in the engine bay? How does the fuel pump sound when its priming?

Have you checked for vacuum leaks? I would think that would cause it to be rich, but its so easy to check it would be good to rule it out. Drill a hole in a PVC pipe cap, pull a valve stem threw it and attach it to where the turbo meets your hot pipe.

It could really be anything at this point, let me know if the ECU tells you anything.

code 55 all clear..1 small leak but i know about it and it would make it rich not lean like you said

[EvoVIII808]

injector / load scale is off with the Z32MAF installed?

[Chase_FerdinRacing]

Well start with the simple things and rule them out one at a time.

Change/gap your spark plugs, coil packs, check timing,

Try to run a fuel pressure gauge into the cabin and make sure fuel pressure is rising as it should with boost.

So my old ecu would always read code 55 and never said anything was wron..when i got the new ecu and chips(same tune) i seen codes 11,12,21...i changed the distributor and holy grap the day before the event th car started and sounded awesome..i went for a drive and it was at 11.5 on afr at WOT

then out of no where.....on the way back completely lean anywhere..14.5 at wot(not going up there again)...17.8-18.0--- at idle and if you slowly raise rpms all the way up is --- lean.. raising the fuel pressure up or down doesnt help.....THIS IS KA24DE

i need people to really read what i rtype to come up with logical answers..

this car has new plugs bkr7e gapped to .030...cap..rotor..wires..coolant temp sensor...autozone maf..tps..minor to 0 vacuum leaks but who cares..it would cause my car to be rich not lean..timings on..maf is pull through..more than 10 inches way...



after the distributor was swapped..the ecu just said 12..which is maf..and i had a regular z maf that was good on..so i got the autozone maf and it still said 12 and still did the same..maf isnt bad..i cleared the codes and it just says 55 so im waiting for a code to come up

Does it sound like this?
