    It's amazing how much a little work does to the throttle response isn't it! I noticed a definite difference right away. Just FYI the Throttle Body Shop has a kit with a new spring for the fuel pressure and a 1/4" spacer for the injectors that's about $45 and it boosts the pressure to about...

    Moparma, how did you make out with the wooden spacer? Is it holding up? I remember the non metallic spacers from the 70's! Talk about ageing myself. I don't remember exactly what they were made from as there were quite a few different ones on the market as this was a new concept. Just...

    Hey Matt Sorry. I did the same thing to my throttle body. You did a great job! Takes a bit of time doesn't it. But it's worth the effort. Good luck with everything. Sent from my Moto G (4) using Tapatalk

    I have add flow matched injectors and an auxiliary fuel pump because of the increased pressure of a new spring for the TBI. I was going to go with the adjustable fuel pressure regulator but figured that I needed 14-16 lbs of pressure which is what the new spring is supposed to be good for...

    It's too bad that Tyler doesn't know how to read. If he did he'd not trash everything I say. Like a 160° thermostat. I'm not going to waste my time or yours explaining it to him. As for "pretty parts" I don't care what they look like as long as they are a good quality and proven part. Hell...

    Do as I did and buy the repair manual from Hayes or Chilton and it'll tell you how to check all the sensors and actuators. It'll give you the readings for the correct values. That's how I discovered my issues which like you were driving me crazy!!! As a side note make sure that you have good...

    If you mean the egr seloniod then yes! Check all the vacuum lines again. The factory elbows on the vacuum lines tend to crack. I used all silicone vac lines no more worries. Did you clean out the egr port's under the egr? How about under the throttle body? All potential trouble spots...

    Head's are going to be aluminum with 200cc runner's. The cam is a special custom grind that is for my eyes only. Everything in steps as money and time allows. I'm not rich like some people who can do anything and everything they want. I'm not in a hurry to get to the end of the project. I...

    MY MODIFIED air cleaner is done by grinding off the inlet pipe for the pre heat tube from the manifold, riviting a cover plate over the opening, cutting the spot welds that hold on the deflector shield next to the air filter and putting a smooth bore 5" tube straight to the grill for direct cold...

    I should have told you guys that this is a High Top Conversion Van!!! You know with all the bells and whistles inside and out. Hence the name Sleeper Van. And if you, and you know who you are think that 255/70/15 is a small tire you definitely need glasses. That's the same size tires that...

    I had the same problems with my 90 G20 Van. Check the two plugs and wires that go into the computer. Mine were bad and it didn't give me any codes when the oxygen sensor and almost all the other sensors were bad!!! I had to put in a new/used harness. Check the oxygen sensor and your egr...

    FYI, That last run of 13.86 was with a blown alternator I discovered when I got home!!! I just ordered a 200amp one for the auxiliary lights, pumps etc. Should be great. Sent from my Moto G (4) using Tapatalk

    One more thing. I didn't get my Chip from chips r us!!! It works off the maf sensor and it does work!!! I don't know what or where you've gotten chips from or what you expected from it. I got mine too work with the other upgrades, not expecting a miracle rather to have an effect on the whole...

    And the last thing I do is throw parts at a job. I researched every part I have ever bought. If it doesn't work I call the factory and work it out!!! Sent from my Moto G (4) using Tapatalk

    Do you have AC? If you do there is definitely a heater control valve. It could be run by vacuum or cable. Find the valve and see if it's hot on both sides of it. Some have a open arm that you can operate by hand, try moving or have someone inside moving the control from hot to cold and see...

    Miscommunication!!! TIME'S ARE FROM 0-65 MPH!!! NOT A QUARTER MILE. And I have seen/felt a BIG improvement already. Tomorrow I'm going to do some more runs, 0-65mph and I'll post the improvement so far although I don't expect the full effect due to the fact that the chip needs a couple of...

    No heat could also be a bad heater control valve, your dashboard controls or a stuck heater door. Just a suggestion. Sent from my Moto G (4) using Tapatalk

    PS, it's not a pig anymore that's for sure as I can smoke the tires without powerbreaking!!! I have owned Vans since 92 and have learned a lot of tricks since then. I'll post pics and a complete list of everything I've done when I have finished. I'm hoping to surprise myself and everyone...

    I would be a dreamer for a 10 second quarter mile!!! I meant from 0-65mph!!! My best so far before the upgrades is 15.97. 10 is doable. Sent from my Moto G (4) using Tapatalk

    Another quick update. I'm going to replace all the sensors in the van. It's only got 123,700 miles and the original owner took very good care of it but he didn't replace anything unless it was bad. He'd put in a new engine and transmission but all the accories are from New!!! I'm going to...

    Your right and I should have stated that in my post. The gears will be the very last thing I do as I'll have to recalibrate the speedo and adjust for tire size which I'm going to try and change if I can find wheels that I like. I'm trying to find a gently used set but in The southern part of...
