QUIKQUEST

I adjusted the fuel pressure to around 38 psi at idle. Now I tried to drive the car today and it was very cold this morning. I let the car warm up , but not that long. I tried to take off and the car fell on its face around 3000 RPM. I put my foot to the floor at this point and NOTHING!! I could only get it back to my house barley tapping the gas pedal. It stumbles ever so slightly at idle, while it was idling i tried to move or play with some of the injector connectors to hear any audible changes in idle and there was none. By this time the car was up to full temp and it then drove all the way thru the RPM range at any throttle with the brief bucking around 3000 or just before boost. What Gives man?????

Wish i could tell you that i did but.... LOL!!! The urges got to me dude!! lost my old phone and some important numbers including yours. Needless to say the boost controller is not hooked up. How have you been? I'll pm you man and get you up on the latest :party0049:

Thanks for the links JP :thumbsup: I will check the filters tomorrow afternoon if it isnt raining out and start there and eliminate that issue. Then move to check to see if I have injector leakage. From what Technology said it sounds really close to what is going on right now with the car. Wouldnt doubt it that its a combination of the two...fuel filters and injectors. I dont know if the previous owner replaced either of them. At least if i do that i will have some piece of mind and know whats in the car for sure

Yeah dude it starts the bucking right around 3000 rpm, also exhibits the same symptom like you described when in third gear. So just replace the prim+secondaries together. Thats probably the best thing to do and arent they sold in pairs anyway? Dont have any starquest buddies nearby besides "Fanta" A.K.A. Justin. But i haven talked to him in awhile. I see that you have links to Fuel injectors, is that a good resource to get them. Have you bought any from them and have you had any issues?? Thanks Man

Is there anything i can do now to see if in fact that is the problem? Did the symptoms i described give you the idea that that may be the cause?

I did just do the "suck test" and it clicked. Didnt think about the hole variences in the diaphram. I dont have a vac tester/gauge on hand. For the cost of the tester it wouldnt hurt to replace the VA unit and eliminate that as a source for the problem, Going outside shortly to plug up the line to VA and see if the problem persists and will get back to report the findings.

What should the fuel pressure be at anyway?? Just for future reference.

I have an aftermarket summit fuel regulator and its reading 32 psi at idle. I just routed the vac lines so that i omit the boost controller and it actually does the same thing but very faintly. It seems like when its at a higher boost it does the same thing but magnified. It could very well be the plugs, because the car does run a little rich under hard acceleration. Doesnt hurt to check , but it feels like something else...

Hey Guys, I know you can get me through this one, after helping me with my other troubleshooting issues. I have a 19C, MSD ign, 2.5 DP, Manual Boost controller. My problem is when i drive the car and stay out of boost mode she runs fantastic, the minute i hammer down on it, it bucks and shutters on me briefly then takes off. The weird thing is that if i play with the throttle about 60% from wide open through the boost..it drives hard!! Otherwise it shutters and bucks on me. I checked my vac advance and thats working properly. My vac lines for the most part are correct. One thing though when i bypass my boost cotroller and run stock , it drives fine???????????????????????????????????????????????? :hangman: Thanks for your help and HAPPY THANKSGIVING TO YOU ALL!!

Mike Your too cool man. The ultimate drawback for a Apt. renter if you a car guy is the ability to work on it on the property. Once my lease is up here, and if my finances are in better standings, a house with a GARAGE is in order. Even if i cant purchase it , i will look to rent it. Nothing like your space,tools and time to work on your car. Nothing is better than to be up late making noises tearing things up in your ride. But anyways, cant tell you how much i appreciate the help man. Also JusP. I will keep you posted on the progress. Again thank you :thumbsup:

I tried to give the starter a slap with a hammer and still did the humming sound as i tried to crank it. However, I did the reverse clutch popping routine and it fired up. When i shut it off it did the same thing with the humming as i lay on the key switch to restart it. So does that mean the teeth on the flywheel are busted or the starter..or BOTH. Man this sucks!! :hangman: Apartment living doesnt allow for much R&R you know...... :confused0024:

I will try to do both of those tests and see what happens, will let you know the results. Thanks

For the last couple of weeks, everytime I go to start the car the starter makes like an electrical arching sound and the car starts. It did that on and off for the last two weeks. Then today i went to start it and all i hear is a humming noise from somewhere under the hood and the car doesnt start. I hear this humming everytime i try to start the car. I assume its the starter making the noise. I checked the voltage at the battery and its fine. Does that sound like more than likely its the starter? Where can I get a good starter from at a resonable price, besides Advance or Autozone. Any suggestions as to where I should start my diag on this problem??

I know of several places around here and already had that in mind. Thanks guys

That is perfect Jus P. Can I still purchase the TB2 kits from FIP? Someone said in this thread that i would have a hard time finding one? There site is up and running and looks like they have them in stock to sell. Where is a reputable retailer or person that in fact i can pick up a real Walbro 255lph to buy. You are definately a great resource about alot of info on these cars JusP. I greatly appreciate the time to thoroughly answer my questions. Based on response on this thread about the TBI2, I am certain to gravitate to that route. TBI2 reviews in the thread from everyone were very helpful in making my decision..again thank you. I like that set-up under the hood Zactec :thumbsup:
