    Volvo 5.0 gxi Stalls at idle. Hard start.

    Volvo wants $300 for oem map. I found a new oem map sensor from a marina next state over for $100. I purchased it and put it in. Was still in original packaging. Way worse ,wouldnt even stay running. Tried letting computer and iac relearn and it was still worse. I figured a few starts and some...

    Volvo 5.0 gxi Stalls at idle. Hard start.

    No the jumpers not in. No one around me has the diacom software for Volvo. They all have merc stuff and merc mechanics. I was tempted to buy the rinda scanner tech mate but since I’m no mechanic I won’t know what any of the data means. Looking online this 2003 engine doesn’t seem to be...

    Volvo 5.0 gxi Stalls at idle. Hard start.

    So I set it exactly.” .020 on each side of throttle plate. It idles high. A steady 1000rpm. No surging no fluctuations. Just a steady high idle. I know I should be down around 600-650 at idle. How much do you think idle will drop once in the water, in gear, with some back pressure ? Will the...

    Volvo 5.0 gxi Stalls at idle. Hard start.

    I found one from summit racing. Should be here in two days. I tried to compare the feeler gauge to small cotter pins and found a one just a hair over .020. It looks like it will still set that stop screw farther than it was from factory. I was the one who scraped the paint off to access the stop...

    I’m looking online and auto stores and can’t find a wire gauge down to .020

    Volvo 5.0 gxi Stalls at idle. Hard start.

    I used a flat plate gauge. I will try a wire gauge. I’ve tried three iac valves now. The cheepo replacement had a different shape pintel. The gm replacement had the same pintle. The oem one had the same pintle. Both the gm replacement and oem replacement work the same and move the same. I found...

    Volvo 5.0 gxi Stalls at idle. Hard start.

    So I finally have a cold engine idle. Yay. Changed many sensors. Changed plugs from .45 gap they put in with new long block to the recommended .60 and engine finally cold idles. The only problem I have now is when engine is under 110 degrees and I go to move throttle just a tiny bit. It will...

    Volvo 5.0 gxi Stalls at idle. Hard start.

    I have no scanner to get any data. It had no iac songe before. I purchased one and put it in. The only change I noticed with the sponge is the iac flow is nice and quite no more loud suction at iac. I haven’t changed plugs yet was going to today. Plugs have about 8hrs on them since the new long...

    Volvo 5.0 gxi Stalls at idle. Hard start.

    Back at it again this summer. Still hard to start stall at idle. It Will idle perfect with tps sensor unplugged. It Will fire up and idle perfect when engine is warm. If engine is cold it will fire up, run for a second, then stall. Fuel pressure is perfect before and during start up. Fuel...

    Volvo 5.0 gxi Stalls at idle. Hard start.

    I tried to open up throttle plate alittle but it didn’t help and brought my idle up higher. When I can idle. When I pull tps off and lay it next to tb, still plugged in, I turn tps wheel all the way “closed” it will fire up and idle perfect. So I even tried closing the throttle plate more to...

    Volvo 5.0 gxi Stalls at idle. Hard start.

    Update. Still have the same no idle to stall problem. I even did a full rebuild on fuel pump. Removed all paint replaced both fuel cells. Replaces check valve on fuel tank. Still starts up runs for a second then stalls. Unplug the tps sensor then Starts up idle perfect until I turn key off...

    Volvo 5.0 gxi Stalls at idle. Hard start.

    Or reset iac ? What if it’s the iac not set correctly and when I unplug tps, that more fuel demand is idling good because iac is not sitting just right. I can see the iac move in tiny increments. And that hissing sound I was hearing is air entering at iac as it trying to to it’s thing to keep...

    Volvo 5.0 gxi Stalls at idle. Hard start.

    Awesome I did that and cleared codes. Now I only get code 12 Normal.yay. Is there a way to reset iac and tps? When searching online I found how to reset tps in gm cars. With the adjusting throttle at pedal and turning ignition on then back off. Would this kind of thing work on these motors...

    Wow that was awesome advice. I didn’t know you could do something like that. Thanks. First code was the 12. Then I got code 21 tps voltage high Then I got code 22 tps voltage is low. I unplugged batteries and going to try again later incase those two codes came from me playing with tps sensor...

    I tested tps with multimeter. Key on - voltage wire at tps is 5v. Back probed the ground and signal wire. Idle sits at .76v , wot sits at 4.47v I don’t have a scanner. Thanks.
