<![CDATA[Need Help!!!]]>ok my car is not as nice as most peoples on here but it's still my baby, so please don't laugh.

Now the problem, we just pulled the engine and dropped it back in. Replaced the (clutch, alternator, valvecover and gasket, new oil pan gasket, new water pump, newer turbo, manifold, intercooler, intercooler piping, blow off valve, new boost controler, new radiator, relocated the battery to the back of the car, and refabricated alot of pieces to make them fit with the new intercooler and piping)

Ok now when we got it all back together, it fired right up, when I took it for a test spin, it won't boost at all, but I can hear the blow off valve going, also when we plug in the harness to the mass air flow sensor the car dies. it also seems to have developed a tick(a very small quiet one) the car dogs really bad and is slow to gain RPM's Also on an minor part, it has flip up head lights that flip up but don't turn on.

if anyone knows how to fix these things please let me know, we were too tired to really look into it, but still don't know why it wasn't working right. after the test drive we just parked it again and figured some time away from it would help clear our minds. also we are wondering if not mounting the mass air flow sensoer flat effects it cause it measure boost according to my shop manual.

any help no matter how small would be appretiated!

Thank you for everything

Since the car dies when you plug the connector in, it's a possibility that the VAF has gone bad.

Im not a damn mechanic, im just a electrician....lol

Um, if you don't know what the MAS does, might want to take it in! heh. It is what the ECU uses to measure the amount of air coming into the engine. It uses that value as one of the MAIN variables in calculating the amount of fuel needed, and hence the injector pulsewidth, etc. FYI don't run the car around without the MAS hooked up, as it just runs off a default sensor parameter and could possibly be very bad for your engine. By the sound of it, you have a HUGE vacuum/boost leak. First thing to check, also definately verify you have it timed correctly, both cam timing and ignition.

Otherwise, PM fallguy.
If you want to just have it done, bring it to SLS, Tintmasters, or roadsounds. Personally, i bought parts from Shane and Nick, both helpful. Never had any experience but only heard the best. Also check out Advanced Autowerx. Jake knows a thing or 2...

So does anyone know where I could take the car to get it checked out, I am on a budget, so someplace that does decent work for a decent price would be what I'm looking for. I would really like to see the car running nice again, but right now I'm so pissed at it I would just sell it. any idea's on shops let me know. Thanks

Try starting the car with the maf plugged in. Will it stay running. Also, try proping the flapper open and see if that helps. Easy way to check for boost leak on a 5-spd car is to unplug the maf and rev the motor. She'll load up with fuel and build some boost. The carb cleaner/starting fluid idea only really works for a vac. leak. Boost leaks often don't appear until under a load (boost).

Also, is the turbo even spinning? What about the exhaust? Clogged?

k, well try those ideas, we r going to tear into it on sunday, so hopefully we can get it to run decent and boost, thanks all for all the help and suggestions, all is appreciated....

get a can of starting fluid and spray it wherever there is a connection at idle. If you spray a hose connector (I.E. intercooler piping) and idle picks up, there is a leak.

I know nothing of the Probe/MX6 engines in particular, but the way it sounds like it isnt running, it reeks of cam timing being off.

Get a book and make sure it's right.

oh yeah, could be igniton timing too, or boost leak. hard to say, what kind of car is it?

the car is a 90 probe gt, im the friend that is helping rebuild it, i was also the one who re-timed the engine, and when i put it back together and it was correct, so I dont think it is that, but i could be wrong... so if it is a boost leak, where would be some good places to start, and would the mass air flow have anything to do with why the car is not running right???

DId you replace the timing belt/chain? does the car backfire? need a little more info here....

btw.. what do you drive?
